Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

    descriptionThe SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.38 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7039: The IP stack in the Linux kernel allowed remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for large crafted packets, as demonstrated by packets that contain only VLAN headers, a related issue to CVE-2016-8666 (bnc#1001486). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure (bnc#1010478). - CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message

"The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.38 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x
    provides an incomplete set of requirements for setattr
    operations that underspecifies removing extended
    privilege attributes, which allowed local users to cause
    a denial of service (capability stripping) via a failed
    invocation of a system call, as demonstrated by using
    chown to remove a capability from the ping or Wireshark
    dumpcap program (bnc#914939).

  - CVE-2015-8964: The tty_set_termios_ldisc function in
    drivers/tty/tty_ldisc.c in the Linux kernel allowed
    local users to obtain sensitive information from kernel
    memory by reading a tty data structure (bnc#1010507).

  - CVE-2016-7039: The IP stack in the Linux kernel allowed
    remote attackers to cause a denial of service (stack
    consumption and panic) or possibly have unspecified
    other impact by triggering use of the GRO path for large
    crafted packets, as demonstrated by packets that contain
    only VLAN headers, a related issue to CVE-2016-8666
    (bnc#1001486).

  - CVE-2016-7042: The proc_keys_show function in
    security/keys/proc.c in the Linux kernel through 4.8.2,
    when the GNU Compiler Collection (gcc) stack protector
    is enabled, uses an incorrect buffer size for certain
    timeout data, which allowed local users to cause a
    denial of service (stack memory corruption and panic) by
    reading the /proc/keys file (bnc#1004517).

  - CVE-2016-7425: The arcmsr_iop_message_xfer function in
    drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did
    not restrict a certain length field, which allowed local
    users to gain privileges or cause a denial of service
    (heap-based buffer overflow) via an
    ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).

  - CVE-2016-7913: The xc2028_set_config function in
    drivers/media/tuners/tuner-xc2028.c in the Linux kernel
    allowed local users to gain privileges or cause a denial
    of service (use-after-free) via vectors involving
    omission of the firmware name from a certain data
    structure (bnc#1010478).

  - CVE-2016-7917: The nfnetlink_rcv_batch function in
    net/netfilter/nfnetlink.c in the Linux kernel did not
    check whether a batch message's length field is large
    enough, which allowed local users to obtain sensitive
    information from kernel memory or cause a denial of
    service (infinite loop or out-of-bounds read) by
    leveraging the CAP_NET_ADMIN capability (bnc#1010444).

  - CVE-2016-8645: The TCP stack in the Linux kernel
    mishandled skb truncation, which allowed local users to
    cause a denial of service (system crash) via a crafted
    application that made sendto system calls, related to
    net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c
    (bnc#1009969).

  - CVE-2016-8666: The IP stack in the Linux kernel allowed
    remote attackers to cause a denial of service (stack
    consumption and panic) or possibly have unspecified
    other impact by triggering use of the GRO path for
    packets with tunnel stacking, as demonstrated by
    interleaved IPv4 headers and GRE headers, a related
    issue to CVE-2016-7039 (bnc#1003964).

  - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux
    kernel allowed local users to bypass integer overflow
    checks, and cause a denial of service (memory
    corruption) or have unspecified other impact, by
    leveraging access to a vfio PCI device file for a
    VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine
    confusion bug (bnc#1007197).

  - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the
    Linux kernel misuses the kzalloc function, which allowed
    local users to cause a denial of service (integer
    overflow) or have unspecified other impact by leveraging
    access to a vfio PCI device file (bnc#1007197).

  - CVE-2016-9793: A bug in SO_{SND|RCV}BUFFORCE
    setsockopt() implementation was fixed, which allowed
    CAP_NET_ADMIN users to cause memory corruption.
    (bsc#1013531).

  - CVE-2016-9919: The icmp6_send function in
    net/ipv6/icmp.c in the Linux kernel omits a certain
    check of the dst data structure, which allowed remote
    attackers to cause a denial of service (panic) via a
    fragmented IPv6 packet (bnc#1014701).

The update package also includes non-security fixes. See advisory for
details.

"An update for kernel-rt is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
requirements.

Security Fix(es) :

* Linux kernel built with the Kernel-based Virtual Machine
(CONFIG_KVM) support is vulnerable to a NULL pointer dereference flaw.
It could occur on x86 platform, when emulating an undefined
instruction. An attacker could use this flaw to crash the host kernel
resulting in DoS. (CVE-2016-8630, Important)

* A race condition issue leading to a use-after-free flaw was found in
the way the raw packet sockets implementation in the Linux kernel
networking subsystem handled synchronization while creating the
TPACKET_V3 ring buffer. A local user able to open a raw packet socket
(requires the CAP_NET_RAW capability) could use this flaw to elevate
their privileges on the system. (CVE-2016-8655, Important)

* A flaw was discovered in the Linux kernel's implementation of VFIO.
An attacker issuing an ioctl can create a situation where memory is
corrupted and modify memory outside of the expected area. This may
overwrite kernel memory and subvert kernel execution. (CVE-2016-9083,
Important)

* The use of a kzalloc with an integer multiplication allowed an
integer overflow condition to be reached in vfio_pci_intrs.c. This
combined with CVE-2016-9083 may allow an attacker to craft an attack
and use unallocated memory, potentially crashing the machine.
(CVE-2016-9084, Moderate)

Red Hat would like to thank Philip Pettersson for reporting
CVE-2016-8655.

Bug Fix(es) :

* Previously, the asynchronous page fault woke code references
spinlocks, which were actually sleeping locks in the RT kernel.
Because of this, when the code was executed from the exception
context, a bug warning appeared on the console. With this update, the
regular wait queue and spinlock code in this area has been modified to
use simple-wait-queue and raw-spinlocks. This code change enables the
asynchronous page fault code to run in a non-preemptable state without
bug warnings. (BZ#1418035)"

    descriptionIt was discovered that the netfilter netlink implementation in the Linux kernel did not properly validate batch messages. A local attacker with the CAP_NET_ADMIN capability could use this to expose sensitive information or cause a denial of service. (CVE-2016-7917) Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build() function in the Linux kernel. A local attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-8632) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. (CVE-2016-9604) Dmitry Vyukov discovered that KVM implementation in the Linux kernel improperly emulated the VMXON instruction. A local attacker in a guest OS could use this to cause a denial of service (memory consumption) in the host OS. (CVE-2017-2596) Daniel Jiang discovered that a race condition existed in the ipv4 ping socket implementation in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-2671) Di Shen discovered that a race condition existed in the perf subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly gain administrative privileges. (CVE-2017-6001) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash) implementation in the Linux kernel did not properly handle a full request queue. A local attacker could use this to cause a denial of service (infinite recursion). (CVE-2017-7618) Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly handle certain long RPC replies. A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-7645) Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889) Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly check for the end of buffer. A remote attacker could use this to craft requests that cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7895) It was discovered that a use-after-free vulnerability existed in the device driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7913) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084).

    descriptionThe SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2015-8963: Race condition in kernel/events/core.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect handling of an swevent data structure during a CPU unplug operation (bnc#1010502). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure (bnc#1010478). - CVE-2016-7914: The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel did not check whether a slot is a leaf, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures, as demonstrated by the keyutils test suite (bnc#1010475). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31349935 (bnc#1014746). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969). - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux kernel allowed local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a

"The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2015-8962: Double free vulnerability in the
    sg_common_write function in drivers/scsi/sg.c in the
    Linux kernel allowed local users to gain privileges or
    cause a denial of service (memory corruption and system
    crash) by detaching a device during an SG_IO ioctl call
    (bnc#1010501).

  - CVE-2015-8963: Race condition in kernel/events/core.c in
    the Linux kernel allowed local users to gain privileges
    or cause a denial of service (use-after-free) by
    leveraging incorrect handling of an swevent data
    structure during a CPU unplug operation (bnc#1010502).

  - CVE-2015-8964: The tty_set_termios_ldisc function in
    drivers/tty/tty_ldisc.c in the Linux kernel allowed
    local users to obtain sensitive information from kernel
    memory by reading a tty data structure (bnc#1010507).

  - CVE-2016-10088: The sg implementation in the Linux
    kernel did not properly restrict write operations in
    situations where the KERNEL_DS option is set, which
    allowed local users to read or write to arbitrary kernel
    memory locations or cause a denial of service
    (use-after-free) by leveraging access to a /dev/sg
    device, related to block/bsg.c and drivers/scsi/sg.c.
    NOTE: this vulnerability exists because of an incomplete
    fix for CVE-2016-9576 (bnc#1017710).

  - CVE-2016-7910: Use-after-free vulnerability in the
    disk_seqf_stop function in block/genhd.c in the Linux
    kernel allowed local users to gain privileges by
    leveraging the execution of a certain stop operation
    even if the corresponding start operation had failed
    (bnc#1010716).

  - CVE-2016-7911: Race condition in the get_task_ioprio
    function in block/ioprio.c in the Linux kernel allowed
    local users to gain privileges or cause a denial of
    service (use-after-free) via a crafted ioprio_get system
    call (bnc#1010711).

  - CVE-2016-7913: The xc2028_set_config function in
    drivers/media/tuners/tuner-xc2028.c in the Linux kernel
    allowed local users to gain privileges or cause a denial
    of service (use-after-free) via vectors involving
    omission of the firmware name from a certain data
    structure (bnc#1010478).

  - CVE-2016-7914: The assoc_array_insert_into_terminal_node
    function in lib/assoc_array.c in the Linux kernel did
    not check whether a slot is a leaf, which allowed local
    users to obtain sensitive information from kernel memory
    or cause a denial of service (invalid pointer
    dereference and out-of-bounds read) via an application
    that uses associative-array data structures, as
    demonstrated by the keyutils test suite (bnc#1010475).

  - CVE-2016-8399: An elevation of privilege vulnerability
    in the kernel networking subsystem could enable a local
    malicious application to execute arbitrary code within
    the context of the kernel. This issue is rated as
    Moderate because it first requires compromising a
    privileged process and current compiler optimizations
    restrict access to the vulnerable code. Product:
    Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:
    A-31349935 (bnc#1014746).

  - CVE-2016-8633: drivers/firewire/net.c in the Linux
    kernel, in certain unusual hardware configurations,
    allowed remote attackers to execute arbitrary code via
    crafted fragmented packets (bnc#1008833).

  - CVE-2016-8645: The TCP stack in the Linux kernel
    mishandled skb truncation, which allowed local users to
    cause a denial of service (system crash) via a crafted
    application that made sendto system calls, related to
    net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c
    (bnc#1009969).

  - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux
    kernel allowed local users to bypass integer overflow
    checks, and cause a denial of service (memory
    corruption) or have unspecified other impact, by
    leveraging access to a vfio PCI device file for a
    VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine
    confusion bug' (bnc#1007197).

  - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the
    Linux kernel misuses the kzalloc function, which allowed
    local users to cause a denial of service (integer
    overflow) or have unspecified other impact by leveraging
    access to a vfio PCI device file (bnc#1007197).

  - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux
    kernel did not properly initialize Code Segment (CS) in
    certain error cases, which allowed local users to obtain
    sensitive information from kernel stack memory via a
    crafted application (bnc#1013038).

  - CVE-2016-9793: The sock_setsockopt function in
    net/core/sock.c in the Linux kernel mishandled negative
    values of sk_sndbuf and sk_rcvbuf, which allowed local
    users to cause a denial of service (memory corruption
    and system crash) or possibly have unspecified other
    impact by leveraging the CAP_NET_ADMIN capability for a
    crafted setsockopt system call with the (1)
    SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531
    1013542).

  - CVE-2016-9806: Race condition in the netlink_dump
    function in net/netlink/af_netlink.c in the Linux kernel
    allowed local users to cause a denial of service (double
    free) or possibly have unspecified other impact via a
    crafted application that made sendmsg system calls,
    leading to a free operation associated with a new dump
    that started earlier than anticipated (bnc#1013540
    1017589).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux
    kernel allowed local users to obtain sensitive
    information from kernel memory or cause a denial of
    service (use-after-free) via a crafted application that
    leverages instruction emulation for fxrstor, fxsave,
    sgdt, and sidt (bsc#1019851).

  - CVE-2017-2583: Fixed broken emulation of 'MOV SS, null
    selector' (bsc#1020602).

  - CVE-2017-5551: Clear SGID bit when setting file
    permissions on tmpfs (bsc#1021258).

The update package also includes non-security fixes. See advisory for
details.

    descriptionIt was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-1000251) It was discovered that the asynchronous I/O (aio) subsystem of the Linux kernel did not properly set permissions on aio memory mappings in some situations. An attacker could use this to more easily exploit other vulnerabilities. (CVE-2016-10044) Baozeng Ding and Andrey Konovalov discovered a race condition in the L2TPv3 IP Encapsulation implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-10200) Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges. (CVE-2016-7097) Sergej Schumilo, Ralf Spenneberg, and Hendrik Schwartke discovered that the key management subsystem in the Linux kernel did not properly allocate memory in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-8650) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084) It was discovered that an information leak existed in __get_user_asm_ex() in the Linux kernel. A local attacker could use this to expose sensitive information.

    descriptionFrom Red Hat Security Advisory 2017:0386 : An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support is vulnerable to a NULL pointer dereference flaw. It could occur on x86 platform, when emulating an undefined instruction. An attacker could use this flaw to crash the host kernel resulting in DoS. (CVE-2016-8630, Important) * A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. (CVE-2016-8655, Important) * A flaw was discovered in the Linux kernel

    descriptionThe openSUSE Leap 42.2 kernel was updated to 4.4.36 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure (bnc#1010478). - CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message

    descriptionUSN-3312-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that the netfilter netlink implementation in the Linux kernel did not properly validate batch messages. A local attacker with the CAP_NET_ADMIN capability could use this to expose sensitive information or cause a denial of service. (CVE-2016-7917) Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build() function in the Linux kernel. A local attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-8632) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. (CVE-2016-9604) Dmitry Vyukov discovered that KVM implementation in the Linux kernel improperly emulated the VMXON instruction. A local attacker in a guest OS could use this to cause a denial of service (memory consumption) in the host OS. (CVE-2017-2596) Daniel Jiang discovered that a race condition existed in the ipv4 ping socket implementation in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-2671) Di Shen discovered that a race condition existed in the perf subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly gain administrative privileges. (CVE-2017-6001) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash) implementation in the Linux kernel did not properly handle a full request queue. A local attacker could use this to cause a denial of service (infinite recursion). (CVE-2017-7618) Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly handle certain long RPC replies. A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-7645) Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889) Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly check for the end of buffer. A remote attacker could use this to craft requests that cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7895) It was discovered that a use-after-free vulnerability existed in the device driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7913) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084).
