"From Red Hat Security Advisory 2018:0395 :

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.

These updated kernel packages include several security issues and
numerous bug fixes, some of which you can see below. Space precludes
documenting all of these bug fixes in this advisory. To see the
complete list of bug fixes, users are directed to the related
Knowledge Article: https://access.redhat.com/articles/3368501.

Security Fix(es) :

* Kernel: KVM: MMU potential stack buffer overrun during page walks
(CVE-2017-12188, Important)

* Kernel: KVM: debug exception via syscall emulation (CVE-2017-7518,
Moderate)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to

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

  - A flaw was found in the Linux kernel's key management
    system where it was possible for an attacker to escalate
    privileges or crash the machine. If a user key gets
    negatively instantiated, an error code is cached in the
    payload area. A negatively instantiated key may be then
    be positively instantiated by updating it with valid
    data. However, the ->update key type method must be
    aware that the error code may be there. (CVE-2015-8539)

  - A flaw was found in the way the Linux KVM module
    processed the trap flag(TF) bit in EFLAGS during
    emulation of the syscall instruction, which leads to a
    debug exception(#DB) being raised in the guest stack. A
    user/process inside a guest could use this flaw to
    potentially escalate their privileges inside the guest.
    Linux guests are not affected by this. (CVE-2017-7518)

  - A vulnerability was found in the Key Management sub
    component of the Linux kernel, where when trying to
    issue a KEYTCL_READ on a negative key would lead to a
    NULL pointer dereference. A local attacker could use
    this flaw to crash the kernel. (CVE-2017-12192)

  - The Linux kernel built with the KVM visualization
    support (CONFIG_KVM), with nested visualization(nVMX)
    feature enabled (nested=1), was vulnerable to a stack
    buffer overflow issue. The vulnerability could occur
    while traversing guest page table entries to resolve
    guest virtual address(gva). An L1 guest could use this
    flaw to crash the host kernel resulting in denial of
    service (DoS) or potentially execute arbitrary code on
    the host to gain privileges on the system.
    (CVE-2017-12188)

  - A flaw was found in the Linux kernel's implementation of
    associative arrays introduced in 3.13. This
    functionality was backported to the 3.10 kernels in Red
    Hat Enterprise Linux 7. The flaw involved a null pointer
    dereference in assoc_array_apply_edit() due to incorrect
    node-splitting in assoc_array implementation. This
    affects the keyring key type and thus key addition and
    link creation operations may cause the kernel to panic.
    (CVE-2017-12193)

  - It was found that fanout_add() in
    'net/packet/af_packet.c' in the Linux kernel, before
    version 4.13.6, allows local users to gain privileges
    via crafted system calls that trigger mishandling of
    packet_fanout data structures, because of a race
    condition (involving fanout_add and packet_do_bind) that
    leads to a use-after-free bug. (CVE-2017-15649)

  - A vulnerability was found in the Linux kernel where the
    keyctl_set_reqkey_keyring() function leaks the thread
    keyring. This allows an unprivileged local user to
    exhaust kernel memory and thus cause a DoS.

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

  - A vulnerability was found in the key management
    subsystem of the Linux kernel. An update on an
    uninstantiated key could cause a kernel panic, leading
    to denial of service (DoS).(CVE-2017-15299)

  - It was found that fanout_add() in
    'net/packet/af_packet.c' in the Linux kernel, before
    version 4.13.6, allows local users to gain privileges
    via crafted system calls that trigger mishandling of
    packet_fanout data structures, because of a race
    condition (involving fanout_add and packet_do_bind)
    that leads to a use-after-free bug.(CVE-2017-15649)

  - The keyctl_read_key function in security/keys/keyctl.c
    in the Key Management subcomponent in the Linux kernel
    before 4.13.5 does not properly consider that a key may
    be possessed but negatively instantiated, which allows
    local users to cause a denial of service (OOPS and
    system crash) via a crafted KEYCTL_READ
    operation.(CVE-2017-12192)

  - The Linux kernel built with the KVM visualization
    support (CONFIG_KVM), with nested visualization(nVMX)
    feature enabled (nested=1), was vulnerable to a stack
    buffer overflow issue. The vulnerability could occur
    while traversing guest page table entries to resolve
    guest virtual address(gva). An L1 guest could use this
    flaw to crash the host kernel resulting in denial of
    service (DoS) or potentially execute arbitrary code on
    the host to gain privileges on the
    system.(CVE-2017-12188)

  - The imon_probe function in drivers/media/rc/imon.c in
    the Linux kernel through 4.13.11 allows local users to
    cause a denial of service (NULL pointer dereference and
    system crash) or possibly have unspecified other impact
    via a crafted USB device.(CVE-2017-16537)

  - drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux
    kernel through 4.13.11 allows local users to cause a
    denial of service (general protection fault and system
    crash) or possibly have unspecified other impact via a
    crafted USB device, related to a missing warm-start
    check and incorrect attach timing
    (dm04_lme2510_frontend_attach versus
    dm04_lme2510_tuner).(CVE-2017-16538)

  - The cx231xx_usb_probe function in
    drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux
    kernel through 4.13.11 allows local users to cause a
    denial of service (NULL pointer dereference and system
    crash) or possibly have unspecified other impact via a
    crafted USB device.(CVE-2017-16536)

  - The usb_get_bos_descriptor function in
    drivers/usb/core/config.c in the Linux kernel before
    4.13.10 allows local users to cause a denial of service
    (out-of-bounds read and system crash) or possibly have
    unspecified other impact via a crafted USB
    device.(CVE-2017-16535)

  - The cdc_parse_cdc_header function in
    drivers/usb/core/message.c in the Linux kernel before
    4.13.6 allows local users to cause a denial of service
    (out-of-bounds read and system crash) or possibly have
    unspecified other impact via a crafted USB
    device.(CVE-2017-16534)

  - The usbhid_parse function in
    drivers/hid/usbhid/hid-core.c in the Linux kernel
    before 4.13.8 allows local users to cause a denial of
    service (out-of-bounds read and system crash) or
    possibly have unspecified other impact via a crafted
    USB device.(CVE-2017-16533)

  - The get_endpoints function in
    drivers/usb/misc/usbtest.c in the Linux kernel through
    4.13.11 allows local users to cause a denial of service
    (NULL pointer dereference and system crash) or possibly
    have unspecified other impact via a crafted USB
    device.(CVE-2017-16532)

  - drivers/usb/core/config.c in the Linux kernel before
    4.13.6 allows local users to cause a denial of service
    (out-of-bounds read and system crash) or possibly have
    unspecified other impact via a crafted USB device,
    related to the USB_DT_INTERFACE_ASSOCIATION
    descriptor.(CVE-2017-16531)

  - The uas driver in the Linux kernel before 4.13.6 allows
    local users to cause a denial of service (out-of-bounds
    read and system crash) or possibly have unspecified
    other impact via a crafted USB device, related to
    drivers/usb/storage/uas-detect.h and
    drivers/usb/storage/uas.c.(CVE-2017-16530)

  - The snd_usb_create_streams function in sound/usb/card.c
    in the Linux kernel before 4.13.6 allows local users to
    cause a denial of service (out-of-bounds read and
    system crash) or possibly have unspecified other impact
    via a crafted USB device.(CVE-2017-16529)

  - sound/core/seq_device.c in the Linux kernel before
    4.13.4 allows local users to cause a denial of service
    (snd_rawmidi_dev_seq_free use-after-free and system
    crash) or possibly have unspecified other impact via a
    crafted USB device.(CVE-2017-16528)

  - sound/usb/mixer.c in the Linux kernel before 4.13.8
    allows local users to cause a denial of service
    (snd_usb_mixer_interrupt use-after-free and system
    crash) or possibly have unspecified other impact via a
    crafted USB device.(CVE-2017-16527)

  - drivers/uwb/uwbd.c in the Linux kernel before 4.13.6
    allows local users to cause a denial of service
    (general protection fault and system crash) or possibly
    have unspecified other impact via a crafted USB
    device.(CVE-2017-16526)

  - The usb_serial_console_disconnect function in
    drivers/usb/serial/console.c in the Linux kernel before
    4.13.8 allows local users to cause a denial of service
    (use-after-free and system crash) or possibly have
    unspecified other impact via a crafted USB device,
    related to disconnection and failed
    setup.(CVE-2017-16525)
