Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    IBSS mode (allows connecting stations together without
    the use of an AP) and connects to another
    STA.(CVE-2019-14897)An out-of-bounds memory write issue
    was found in the Linux Kernel, version 3.13 through
    5.4, in the way the Linux kernel's KVM hypervisor
    handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request
    to get CPUID features emulated by the KVM hypervisor. A
    user or process able to access the '/dev/kvm' device
    could use this flaw to crash the system, resulting in a
    denial of service.(CVE-2019-19332)Improper invalidation
    for page table updates by a virtual guest operating
    system for multiple Intel(R) Processors may allow an
    authenticated user to potentially enable denial of
    service of the host system via local
    access.(CVE-2018-12207)In the Android kernel in the
    video driver there is a use after free due to a race
    condition. This could lead to local escalation of
    privilege with no additional execution privileges
    needed. User interaction is not needed for
    exploitation.(CVE-2019-9458)In the AppleTalk subsystem
    in the Linux kernel before 5.1, there is a potential
    NULL pointer dereference because register_snap_client
    may return NULL. This will lead to denial of service in
    net/appletalk/aarp.c and net/appletalk/ddp.c, as
    demonstrated by unregister_snap_client, aka
    CID-9804501fa122.(CVE-2019-19227)In the Linux kernel
    5.0.21, mounting a crafted btrfs filesystem image,
    performing some operations, and then making a syncfs
    system call can lead to a use-after-free in
    __mutex_lock in kernel/locking/mutex.c. This is related
    to mutex_can_spin_on_owner in kernel/locking/mutex.c,
    __btrfs_qgroup_free_meta in fs/btrfs/qgroup.c, and
    btrfs_insert_delayed_items in
    fs/btrfs/delayed-inode.c.(CVE-2019-19813)In the Linux
    kernel 5.4.0-rc2, there is a use-after-free (read) in
    the __blk_add_trace function in kernel/trace/blktrace.c
    (which is used to fill out a blk_io_trace structure and
    place it in a per-cpu sub-buffer).(CVE-2019-19768)In
    the Linux kernel before 5.0.6, there is a NULL pointer
    dereference in drop_sysctl_table() in
    fs/proc/proc_sysctl.c, related to put_links, aka
    CID-23da9588037e.(CVE-2019-20054)In the Linux kernel
    before 5.2.9, there is an info-leak bug that can be
    caused by a malicious USB device in the
    driverset/can/usb/peak_usb/pcan_usb_pro.c driver, aka
    CID-ead16e53c2f0.(CVE-2019-19536)In the Linux kernel
    before 5.3.11, there is an info-leak bug that can be
    caused by a malicious USB device in the
    driverset/can/usb/peak_usb/pcan_usb_core.c driver, aka
    CID-f7a1337f0d29.(CVE-2019-19534)In the Linux kernel

    4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an
    authenticated user to potentially enable escalation of
    privilege via local access.(CVE-2019-0155)Insufficient
    input validation in Kernel Mode Driver in Intel(R) i915
    Graphics for Linux before version 5.0 may allow an
    authenticated user to potentially enable escalation of
    privilege via local
    access.(CVE-2019-11085)kernel/sched/fair.c in the Linux
    kernel before 5.3.9, when cpu.cfs_quota_us is used
    (e.g., with Kubernetes), allows attackers to cause a
    denial of service against non-cpu-bound applications by
    generating a workload that triggers unwanted slice
    expiration, aka CID-de53fd7aedb1. (In other words,
    although this slice expiration would typically be seen
    with benign workloads, it is possible that an attacker
    could calculate how many stray requests are required to
    force an entire Kubernetes cluster into a
    low-performance state caused by slice expiration, and
    ensure that a DDoS attack sent that number of stray
    requests. An attack does not affect the stability of
    the kernel it only causes mismanagement of application
    execution.)(CVE-2019-19922)The evm_verify_hmac function
    in security/integrity/evm/evm_main.c in the Linux
    kernel before 4.5 does not properly copy data, which
    makes it easier for local users to forge MAC values via
    a timing side-channel attack.(CVE-2016-2085)The
    pcpu_embed_first_chunk function in mm/percpu.c in the
    Linux kernel through 4.14.14 allows local users to
    obtain sensitive address information by reading dmesg
    data from a 'pages/cpu' printk call.(CVE-2018-5995)TSX
    Asynchronous Abort condition on some CPUs utilizing
    speculative execution may allow an authenticated user
    to potentially enable information disclosure via a side
    channel with local access.(CVE-2019-11135)An issue was
    discovered in drivers/scsi/aacraid/commctrl.c in the
    Linux kernel before 4.13. There is potential exposure
    of kernel stack memory because aac_send_raw_srb does
    not initialize the reply structure.(CVE-2017-18549)An
    issue was discovered in drivers/scsi/aacraid/commctrl.c
    in the Linux kernel before 4.13. There is potential
    exposure of kernel stack memory because
    aac_get_hba_info does not initialize the hbainfo
    structure.(CVE-2017-18550)In the Linux kernel through
    4.15.4, the floppy driver reveals the addresses of
    kernel functions and global variables using printk
    calls within the function show_floppy in
    drivers/block/floppy.c. An attacker can read this
    information from dmesg and use the addresses to find
    the locations of kernel code and data and bypass kernel
    security protections such as KASLR.(CVE-2018-7273)A
    heap-based buffer overflow was discovered in the Linux
    kernel, all versions 3.x.x and 4.x.x before 4.18.0, in
    Marvell WiFi chip driver. The flaw could occur when the
    station attempts a connection negotiation during the
    handling of the remote devices country settings. This
    could allow the remote device to cause a denial of
    service (system crash) or possibly execute arbitrary
    code.(CVE-2019-14895)The Linux kernel before 5.4.1 on
    powerpc allows Information Exposure because the
    Spectre-RSB mitigation is not in place for all
    applicable CPUs, aka CID-39e72bf96f58. This is related
    to arch/powerpc/kernel/entry_64.S and
    arch/powerpc/kernel/security.c.(CVE-2019-18660)In the
    Linux kernel 5.0.21, mounting a crafted ext4 filesystem
    image, performing some operations, and unmounting can
    lead to a use-after-free in ext4_put_super in
    fs/ext4/super.c, related to dump_orphan_list in
    fs/ext4/super.c.(CVE-2019-19447)In the Linux kernel
    through 5.4.6, there is a NULL pointer dereference in
    drivers/scsi/libsas/sas_discover.c because of
    mishandling of port disconnection during discovery,
    related to a PHY down race condition, aka
    CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel
    before 5.1.6, there is a use-after-free in cpia2_exit()
    in drivers/media/usb/cpia2/cpia2_v4l.c that will cause
    denial of service, aka
    CID-dea37a972655.(CVE-2019-19966)An exploitable
    denial-of-service vulnerability exists in the Linux
    kernel prior to mainline 5.3. An attacker could exploit
    this vulnerability by triggering AP to send IAPP
    location updates for stations before the required
    authentication process has completed. This could lead
    to different denial-of-service scenarios, either by
    causing CAM table attacks, or by leading to traffic
    flapping if faking already existing clients in other
    nearby APs of the same wireless infrastructure. An
    attacker can forge Authentication and Association
    Request packets to trigger this
    vulnerability.(CVE-2019-5108)mwifiex_tm_cmd in
    drivers/net/wireless/marvell/mwifiex/cfg80211.c in the
    Linux kernel before 5.1.6 has some error-handling cases
    that did not free allocated hostcmd memory, aka
    CID-003b686ace82. This will cause a memory leak and
    denial of service.(CVE-2019-20095)

"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected
by multiple vulnerabilities:

  - The bnep_sock_ioctl function in
    net/bluetooth/bnep/sock.c in the Linux kernel before
    2.6.39 does not ensure that a certain device field ends
    with a '\0' character, which allows local users to
    obtain potentially sensitive information from kernel
    stack memory, or cause a denial of service (BUG and
    system crash), via a BNEPCONNADD command.
    (CVE-2011-1079)

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux
    kernel before 4.8. A use-after-free is caused by the
    functions gfs2_clear_rgrpd and read_rindex_entry.
    (CVE-2016-10905)

  - An issue was discovered in
    drivers/scsi/aacraid/commctrl.c in the Linux kernel
    before 4.13. There is potential exposure of kernel stack
    memory because aac_get_hba_info does not initialize the
    hbainfo structure. (CVE-2017-18550)

  - An issue was discovered in the Linux kernel before
    4.14.11. A double free may be caused by the function
    allocate_trace_buffer in the file kernel/trace/trace.c.
    (CVE-2017-18595)

  - Improper invalidation for page table updates by a
    virtual guest operating system for multiple Intel(R)
    Processors may allow an authenticated user to
    potentially enable denial of service of the host system
    via local access. (CVE-2018-12207)

  - An issue was discovered in the Linux kernel before 4.20.
    There is a race condition in smp_task_timedout() and
    smp_task_done() in drivers/scsi/libsas/sas_expander.c,
    leading to a use-after-free. (CVE-2018-20836)

  - An issue was discovered in the Linux kernel before
    4.18.7. In create_qp_common in
    drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp
    was never initialized, resulting in a leak of stack
    memory to userspace. (CVE-2018-20855)

  - An issue was discovered in fs/xfs/xfs_super.c in the
    Linux kernel before 4.18. A use after free exists,
    related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - In the tun subsystem in the Linux kernel before 4.13.14,
    dev_get_valid_name is not called before
    register_netdevice. This allows local users to cause a
    denial of service (NULL pointer dereference and panic)
    via an ioctl(TUNSETIFF) call with a dev name containing
    a / character. This is similar to CVE-2013-4343.
    (CVE-2018-7191)

  - Insufficient access control in subsystem for Intel (R)
    processor graphics in 6th, 7th, 8th and 9th Generation
    Intel(R) Core(TM) Processor Families; Intel(R)
    Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900
    Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100
    Processor Families may allow an authenticated user to
    potentially enable denial of service via local access.
    (CVE-2019-0154)

  - Insufficient access control in a subsystem for Intel (R)
    processor graphics in 6th, 7th, 8th and 9th Generation
    Intel(R) Core(TM) Processor Families; Intel(R)
    Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900
    Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and
    E-2200 Processor Families; Intel(R) Graphics Driver for
    Windows before 26.20.100.6813 (DCH) or 26.20.100.6812
    and before 21.20.x.5077 (aka15.45.5077), i915 Linux
    Driver for Intel(R) Processor Graphics before versions
    5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may
    allow an authenticated user to potentially enable
    escalation of privilege via local access.
    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing
    speculative execution may allow an authenticated user to
    potentially enable information disclosure via a side
    channel with local access. (CVE-2019-11135)

  - The Linux kernel before 5.1-rc5 allows page->_refcount
    reference count overflow, with resultant use-after-free
    issues, if about 140 GiB of RAM exists. This is related
    to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
    include/linux/mm.h, include/linux/pipe_fs_i.h,
    kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can
    occur with FUSE requests. (CVE-2019-11487)

  - The do_hidp_sock_ioctl function in
    net/bluetooth/hidp/sock.c in the Linux kernel before
    5.0.15 allows a local user to obtain potentially
    sensitive information from kernel stack memory via a
    HIDPCONNADD command, because a name field may not end
    with a '\0' character. (CVE-2019-11884)

  - ** DISPUTED ** An issue was discovered in
    drm_load_edid_firmware in
    drivers/gpu/drm/drm_edid_load.c in the Linux kernel
    through 5.1.5. There is an unchecked kstrdup of fwstr,
    which might allow an attacker to cause a denial of
    service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a
    vulnerability because kstrdup() returning NULL is
    handled sufficiently and there is no chance for a NULL
    pointer dereference. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before
    5.2.3. There is a use-after-free caused by a malicious
    USB device in the drivers/media/usb/dvb-usb/dvb-usb-
    init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in
    fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS
    partially wedges when a chgrp fails on account of being
    out of disk quota. xfs_setattr_nonsize is failing to
    unlock the ILOCK after the xfs_qm_vop_chown_reserve call
    fails. This is primarily a local DoS attack vector, but
    it might result as well in remote DoS if the XFS
    filesystem is exported for instance via NFS.
    (CVE-2019-15538)

  - In the Linux kernel before 5.1.13, there is a memory
    leak in drivers/scsi/libsas/sas_expander.c when SAS
    expander discovery fails. This will cause a BUG and
    denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before
    5.0.1. There is a memory leak in
    register_queue_kobjects() in net/core/net-sysfs.c, which
    will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before
    5.0.4. The 9p filesystem did not protect i_size_write()
    properly, which causes an i_size_read() infinite loop
    and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in
    drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel
    through 5.3.2. The cxgb4 driver is directly calling
    dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of
    Service, exploitable if this driver is used on an
    architecture for which this stack/DMA interaction has
    security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application
    is not accounted by the cgroups subsystem. An attacker
    can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be
    vulnerable. (CVE-2019-3874)

"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by
multiple vulnerabilities:

  - The bnep_sock_ioctl function in
    net/bluetooth/bnep/sock.c in the Linux kernel before
    2.6.39 does not ensure that a certain device field ends
    with a '\0' character, which allows local users to
    obtain potentially sensitive information from kernel
    stack memory, or cause a denial of service (BUG and
    system crash), via a BNEPCONNADD command.
    (CVE-2011-1079)

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux
    kernel before 4.8. A use-after-free is caused by the
    functions gfs2_clear_rgrpd and read_rindex_entry.
    (CVE-2016-10905)

  - An issue was discovered in
    drivers/scsi/aacraid/commctrl.c in the Linux kernel
    before 4.13. There is potential exposure of kernel stack
    memory because aac_get_hba_info does not initialize the
    hbainfo structure. (CVE-2017-18550)

  - An issue was discovered in the Linux kernel before
    4.14.11. A double free may be caused by the function
    allocate_trace_buffer in the file kernel/trace/trace.c.
    (CVE-2017-18595)

  - Improper invalidation for page table updates by a
    virtual guest operating system for multiple Intel(R)
    Processors may allow an authenticated user to
    potentially enable denial of service of the host system
    via local access. (CVE-2018-12207)

  - An issue was discovered in the Linux kernel before 4.20.
    There is a race condition in smp_task_timedout() and
    smp_task_done() in drivers/scsi/libsas/sas_expander.c,
    leading to a use-after-free. (CVE-2018-20836)

  - An issue was discovered in the Linux kernel before
    4.18.7. In create_qp_common in
    drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp
    was never initialized, resulting in a leak of stack
    memory to userspace. (CVE-2018-20855)

  - An issue was discovered in fs/xfs/xfs_super.c in the
    Linux kernel before 4.18. A use after free exists,
    related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - In the tun subsystem in the Linux kernel before 4.13.14,
    dev_get_valid_name is not called before
    register_netdevice. This allows local users to cause a
    denial of service (NULL pointer dereference and panic)
    via an ioctl(TUNSETIFF) call with a dev name containing
    a / character. This is similar to CVE-2013-4343.
    (CVE-2018-7191)

  - Insufficient access control in subsystem for Intel (R)
    processor graphics in 6th, 7th, 8th and 9th Generation
    Intel(R) Core(TM) Processor Families; Intel(R)
    Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900
    Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100
    Processor Families may allow an authenticated user to
    potentially enable denial of service via local access.
    (CVE-2019-0154)

  - Insufficient access control in a subsystem for Intel (R)
    processor graphics in 6th, 7th, 8th and 9th Generation
    Intel(R) Core(TM) Processor Families; Intel(R)
    Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900
    Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and
    E-2200 Processor Families; Intel(R) Graphics Driver for
    Windows before 26.20.100.6813 (DCH) or 26.20.100.6812
    and before 21.20.x.5077 (aka15.45.5077), i915 Linux
    Driver for Intel(R) Processor Graphics before versions
    5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may
    allow an authenticated user to potentially enable
    escalation of privilege via local access.
    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing
    speculative execution may allow an authenticated user to
    potentially enable information disclosure via a side
    channel with local access. (CVE-2019-11135)

  - The Linux kernel before 5.1-rc5 allows page->_refcount
    reference count overflow, with resultant use-after-free
    issues, if about 140 GiB of RAM exists. This is related
    to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
    include/linux/mm.h, include/linux/pipe_fs_i.h,
    kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can
    occur with FUSE requests. (CVE-2019-11487)

  - The do_hidp_sock_ioctl function in
    net/bluetooth/hidp/sock.c in the Linux kernel before
    5.0.15 allows a local user to obtain potentially
    sensitive information from kernel stack memory via a
    HIDPCONNADD command, because a name field may not end
    with a '\0' character. (CVE-2019-11884)

  - ** DISPUTED ** An issue was discovered in
    drm_load_edid_firmware in
    drivers/gpu/drm/drm_edid_load.c in the Linux kernel
    through 5.1.5. There is an unchecked kstrdup of fwstr,
    which might allow an attacker to cause a denial of
    service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a
    vulnerability because kstrdup() returning NULL is
    handled sufficiently and there is no chance for a NULL
    pointer dereference. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before
    5.2.3. There is a use-after-free caused by a malicious
    USB device in the drivers/media/usb/dvb-usb/dvb-usb-
    init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in
    fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS
    partially wedges when a chgrp fails on account of being
    out of disk quota. xfs_setattr_nonsize is failing to
    unlock the ILOCK after the xfs_qm_vop_chown_reserve call
    fails. This is primarily a local DoS attack vector, but
    it might result as well in remote DoS if the XFS
    filesystem is exported for instance via NFS.
    (CVE-2019-15538)

  - In the Linux kernel before 5.1.13, there is a memory
    leak in drivers/scsi/libsas/sas_expander.c when SAS
    expander discovery fails. This will cause a BUG and
    denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before
    5.0.1. There is a memory leak in
    register_queue_kobjects() in net/core/net-sysfs.c, which
    will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before
    5.0.4. The 9p filesystem did not protect i_size_write()
    properly, which causes an i_size_read() infinite loop
    and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in
    drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel
    through 5.3.2. The cxgb4 driver is directly calling
    dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of
    Service, exploitable if this driver is used on an
    architecture for which this stack/DMA interaction has
    security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application
    is not accounted by the cgroups subsystem. An attacker
    can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be
    vulnerable. (CVE-2019-3874)

  - Linux Linux kernel version at least v4.8 onwards,
    probably well before contains a Insufficient input
    validation vulnerability in bnx2x network card driver
    that can result in DoS: Network card firmware assertion
    takes card off-line. This attack appear to be
    exploitable via An attacker on a must pass a very
    large, specially crafted packet to the bnx2x card. This
    can be done from an untrusted guest
    VM..(CVE-2018-1000026)

  - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel
    5.2.14 does not check the alloc_workqueue return value,
    leading to a NULL pointer dereference.(CVE-2019-16233)

  - The SCTP socket buffer used by a userspace application
    is not accounted by the cgroups subsystem. An attacker
    can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be
    vulnerable.(CVE-2019-3874)

  - fs/ext4/extents.c in the Linux kernel through 5.1.2
    does not zero out the unused memory region in the
    extent tree block, which might allow local users to
    obtain sensitive information by reading uninitialized
    data in the filesystem.(CVE-2019-11833)

  - A memory leak in the ql_alloc_large_buffers() function
    in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux
    kernel before 5.3.5 allows local users to cause a
    denial of service (memory consumption) by triggering
    pci_dma_mapping_error() failures, aka
    CID-1acb8f2a7a9f.(CVE-2019-18806)

  - An issue was discovered in the Linux kernel before
    5.0.11. fm10k_init_module in
    drivers/net/ethernet/intel/fm10k/fm10k_main.c has a
    NULL pointer dereference because there is no -ENOMEM
    upon an alloc_workqueue failure.(CVE-2019-15924)

  - An issue was discovered in the Linux kernel before
    5.0.1. There is a memory leak in
    register_queue_kobjects() in net/core/net-sysfs.c,
    which will cause denial of service.(CVE-2019-15916)

  - An issue was discovered in the Linux kernel before
    5.0.14. There is a NULL pointer dereference caused by a
    malicious USB device in the drivers/usb/misc/yurex.c
    driver.(CVE-2019-15216)

  - An issue was discovered in the Linux kernel before
    5.1.8. There is a double-free caused by a malicious USB
    device in the drivers/usb/misc/rio500.c
    driver.(CVE-2019-15212)

  - An issue was discovered in drivers/scsi/qedi/qedi_dbg.c
    in the Linux kernel before 5.1.12. In the qedi_dbg_*
    family of functions, there is an out-of-bounds
    read.(CVE-2019-15090)

  - An issue was discovered in the Linux kernel before 5.0.
    The function __mdiobus_register() in
    drivers/net/phy/mdio_bus.c calls put_device(), which
    will trigger a fixed_mdio_bus_init use-after-free. This
    will cause a denial of service.(CVE-2019-12819)

  - ** DISPUTED ** An issue was discovered in the
    MPT3COMMAND case in _ctl_ioctl_main in
    drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel
    through 5.1.5. It allows local users to cause a denial
    of service or possibly have unspecified other impact by
    changing the value of ioc_number between two kernel
    reads of that value, aka a 'double fetch'
    vulnerability. NOTE: a third party reports that this is
    unexploitable because the doubly fetched value is not
    used.(CVE-2019-12456)

  - An issue was discovered in drm_load_edid_firmware in
    drivers/gpu/drm/drm_edid_load.c in the Linux kernel
    through 5.1.5. There is an unchecked kstrdup of fwstr,
    which might allow an attacker to cause a denial of
    service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a
    vulnerability because kstrdup() returning NULL is
    handled sufficiently and there is no chance for a NULL
    pointer dereference.(CVE-2019-12382)

  - In the Linux Kernel before version 4.15.8, 4.14.25,
    4.9.87, 4.4.121, 4.1.51, and 3.2.102, an error in the
    '_sctp_make_chunk()' function
    (net/sctp/sm_make_chunk.c) when handling SCTP packets
    length can be exploited to cause a kernel
    crash.(CVE-2018-5803)

  - An issue was discovered in the Linux kernel before
    4.14.11. A double free may be caused by the function
    allocate_trace_buffer in the file
    kernel/trace/trace.c.(CVE-2017-18595)

  - An issue was discovered in drivers/i2c/i2c-core-smbus.c
    in the Linux kernel before 4.14.15. There is an out of
    bounds write in the function
    i2c_smbus_xfer_emulated.(CVE-2017-18551)

  - An issue was discovered in
    drivers/scsi/aacraid/commctrl.c in the Linux kernel
    before 4.13. There is potential exposure of kernel
    stack memory because aac_get_hba_info does not
    initialize the hbainfo structure.(CVE-2017-18550)

  - An issue was discovered in
    drivers/scsi/aacraid/commctrl.c in the Linux kernel
    before 4.13. There is potential exposure of kernel
    stack memory because aac_send_raw_srb does not
    initialize the reply structure.(CVE-2017-18549)
