Summary

Race condition in the vop_ioctl function in drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver in the Linux kernel before 4.6.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (memory corruption and system crash) by changing a certain header, aka a "double fetch" vulnerability.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

Kangjie Lu discovered an information leak in the Reliable Datagram
Sockets (RDS) implementation in the Linux kernel. A local attacker
could use this to obtain potentially sensitive information from kernel
memory. (CVE-2016-5244)

Yue Cao et al discovered a flaw in the TCP implementation's handling
of challenge acks in the Linux kernel. A remote attacker could use
this to cause a denial of service (reset connection) or inject content
into an TCP stream. (CVE-2016-5696)

Pengfei Wang discovered a race condition in the MIC VOP driver in the
Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or obtain potentially sensitive information
from kernel memory. (CVE-2016-5728)

Cyril Bur discovered that on PowerPC platforms, the Linux kernel
mishandled transactional memory state on exec(). A local attacker
could use this to cause a denial of service (system crash) or possibly

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01, allows local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721.(CVE-2016-0823i1/4%0 - drivers/hid/hid-steelseries.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_STEELSERIES is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.(CVE-2013-2891i1/4%0 - The overlayfs implementation in the Linux kernel through 4.5.2 does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory.(CVE-2016-1575i1/4%0 - Integer overflow in the vc4_get_bcl function in drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM driver in the Linux kernel before 4.9.7 allows local users to cause a denial of service or possibly have unspecified other impact via a crafted size value in a VC4_SUBMIT_CL ioctl call.(CVE-2017-5576i1/4%0 - The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address.(CVE-2013-6368i1/4%0 - It was found that the code in net/sctp/socket.c in the Linux kernel through 4.10.1 does not properly restrict association peel-off operations during certain wait states, which allows local users to cause a denial of service (invalid unlock and double free) via a multithreaded application. This vulnerability was introduced by CVE-2017-5986 fix (commit 2dcab5984841).(CVE-2017-6353i1/4%0 - net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function.(CVE-2014-2523i1/4%0 - Race condition vulnerability was found in drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver in the Linux kernel before 4.6.1. MIC VOP driver does two successive reads from user space to read a variable length data structure. Local user can obtain sensitive information from kernel memory or can cause DoS by corrupting kernel memory if the data structure changes between the two reads.(CVE-2016-5728i1/4%0 - An issue was discovered in the btrfs filesystem code in the Linux kernel. An invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image is due to a lack of block group item validation in check_leaf_item() in fs/btrfs/tree-checker.c function. This could lead to a system crash and a denial of service.(CVE-2018-14613i1/4%0 - A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from a #SS (stack segment) fault on an erroneous return to user space. A local, unprivileged user could use this flaw to escalate their privileges on the system.(CVE-2014-9322i1/4%0 - The keyring_search_aux function in security/keys/keyring.c in the Linux kernel allows local users to cause a denial of service via a request_key system call for the

"According to the versions of the kernel packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - The pagemap_open function in fs/proc/task_mmu.c in the
    Linux kernel before 3.19.3, as used in Android 6.0.1
    before 2016-03-01, allows local users to obtain
    sensitive physical-address information by reading a
    pagemap file, aka Android internal bug
    25739721.(CVE-2016-0823i1/4%0

  - drivers/hid/hid-steelseries.c in the Human Interface
    Device (HID) subsystem in the Linux kernel through
    3.11, when CONFIG_HID_STEELSERIES is enabled, allows
    physically proximate attackers to cause a denial of
    service (heap-based out-of-bounds write) via a crafted
    device.(CVE-2013-2891i1/4%0

  - The overlayfs implementation in the Linux kernel
    through 4.5.2 does not properly maintain POSIX ACL
    xattr data, which allows local users to gain privileges
    by leveraging a group-writable setgid
    directory.(CVE-2016-1575i1/4%0

  - Integer overflow in the vc4_get_bcl function in
    drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM
    driver in the Linux kernel before 4.9.7 allows local
    users to cause a denial of service or possibly have
    unspecified other impact via a crafted size value in a
    VC4_SUBMIT_CL ioctl call.(CVE-2017-5576i1/4%0

  - The KVM subsystem in the Linux kernel through 3.12.5
    allows local users to gain privileges or cause a denial
    of service (system crash) via a VAPIC synchronization
    operation involving a page-end
    address.(CVE-2013-6368i1/4%0

  - It was found that the code in net/sctp/socket.c in the
    Linux kernel through 4.10.1 does not properly restrict
    association peel-off operations during certain wait
    states, which allows local users to cause a denial of
    service (invalid unlock and double free) via a
    multithreaded application. This vulnerability was
    introduced by CVE-2017-5986 fix (commit
    2dcab5984841).(CVE-2017-6353i1/4%0

  - net/netfilter/nf_conntrack_proto_dccp.c in the Linux
    kernel through 3.13.6 uses a DCCP header pointer
    incorrectly, which allows remote attackers to cause a
    denial of service (system crash) or possibly execute
    arbitrary code via a DCCP packet that triggers a call
    to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error
    function.(CVE-2014-2523i1/4%0

  - Race condition vulnerability was found in
    drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver
    in the Linux kernel before 4.6.1. MIC VOP driver does
    two successive reads from user space to read a variable
    length data structure. Local user can obtain sensitive
    information from kernel memory or can cause DoS by
    corrupting kernel memory if the data structure changes
    between the two reads.(CVE-2016-5728i1/4%0

  - An issue was discovered in the btrfs filesystem code in
    the Linux kernel. An invalid pointer dereference in
    io_ctl_map_page() when mounting and operating a crafted
    btrfs image is due to a lack of block group item
    validation in check_leaf_item() in
    fs/btrfs/tree-checker.c function. This could lead to a
    system crash and a denial of service.(CVE-2018-14613i1/4%0

  - A flaw was found in the way the Linux kernel handled GS
    segment register base switching when recovering from a
    #SS (stack segment) fault on an erroneous return to
    user space. A local, unprivileged user could use this
    flaw to escalate their privileges on the
    system.(CVE-2014-9322i1/4%0

  - The keyring_search_aux function in
    security/keys/keyring.c in the Linux kernel allows
    local users to cause a denial of service via a
    request_key system call for the 'dead' key
    type.(CVE-2017-6951i1/4%0

  - A flaw was found in the way the Linux kernel's XFS file
    system handled replacing of remote attributes under
    certain conditions. A local user with access to XFS
    file system mount could potentially use this flaw to
    escalate their privileges on the
    system.(CVE-2015-0274i1/4%0

  - A memory leak in the kernel_read_file function in
    fs/exec.c in the Linux kernel through 4.20.11 allows
    attackers to cause a denial of service (memory
    consumption) by triggering vfs_read
    failures.(CVE-2019-8980i1/4%0

  - A flaw was found in the kernel's implementation of the
    Berkeley Packet Filter (BPF). A local attacker could
    craft BPF code to crash the system by creating a
    situation in which the JIT compiler would fail to
    correctly optimize the JIT image on the last pass. This
    would lead to the CPU executing instructions that were
    not part of the JIT code.(CVE-2015-4700i1/4%0

  - A security flaw was discovered in
    nl80211_set_rekey_data() function in the Linux kernel
    since v3.1-rc1 through v4.13. This function does not
    check whether the required attributes are present in a
    netlink request. This request can be issued by a user
    with CAP_NET_ADMIN privilege and may result in NULL
    dereference and a system crash.(CVE-2017-12153i1/4%0

  - The atyfb_ioctl function in
    drivers/video/fbdev/aty/atyfb_base.c in the Linux
    kernel through 4.12.10 does not initialize a certain
    data structure, which allows local users to obtain
    sensitive information from kernel stack memory by
    reading locations associated with padding
    bytes.(CVE-2017-14156i1/4%0

  - kernel/events/core.c in the performance subsystem in
    the Linux kernel before 4.0 mismanages locks during
    certain migrations, which allows local users to gain
    privileges via a crafted application, aka Android
    internal bug 31095224.(CVE-2016-6787i1/4%0

  - The ioresources_init function in kernel/resource.c in
    the Linux kernel through 4.7, as used in Android before
    2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak
    permissions for /proc/iomem, which allows local users
    to obtain sensitive information by reading this file,
    aka Android internal bug 28814213 and Qualcomm internal
    bug CR786116. NOTE: the permissions may be intentional
    in most non-Android contexts.(CVE-2015-8944i1/4%0

  - Race condition in the ioctl_file_dedupe_range function
    in fs/ioctl.c in the Linux kernel through 4.7 allows
    local users to cause a denial of service (heap-based
    buffer overflow) or possibly gain privileges by
    changing a certain count value, aka a 'double fetch'
    vulnerability.(CVE-2016-6516i1/4%0

  - It was found that the timer functionality in the Linux
    kernel ALSA subsystem is prone to a race condition
    between read and ioctl system call handlers, resulting
    in an uninitialized memory disclosure to user space. A
    local user could use this flaw to read information
    belonging to other users.(CVE-2017-1000380i1/4%0
