  script_tag(name:"insight", value:"This kernel update is based on the upstream 4.14.100 and fixes at least
the following security issues:

A use-after-free issue was found in the way the Linux kernel's KVM
hypervisor processed posted interrupts when nested(=1) virtualization is
enabled. In nested_get_vmcs12_pages(), in case of an error while
processing posted interrupt address, it unmaps the 'pi_desc_page' without
resetting 'pi_desc' descriptor address, which is later used in
pi_test_and_clear_on(). A guest user/process could use this flaw to crash
the host kernel resulting in DoS or potentially gain privileged access to
a system (CVE-2018-16882).

A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares
mounted in different network namespaces at the same time can make
bc_svc_process() use wrong back-channel IDs and cause a use-after-free
vulnerability. Thus a malicious container user can cause a host kernel
memory corruption and a system panic. Due to the nature of the flaw,
privilege escalation cannot be fully ruled out (CVE-2018-16884).

A flaw was found in the Linux kernel in the function hso_probe() which
reads if_num value from the USB device (as an u8) and uses it without a
length check to index an array, resulting in an OOB memory read in
hso_probe() or hso_get_config_data(). An attacker with a forged USB
device and physical access to a system (needed to connect such a device)
can cause a system crash and a denial of service (CVE-2018-19985).

An issue was discovered in can_can_gw_rcv in net/can/gw.c in the Linux
kernel through 4.19.13. The CAN frame modification rules allow bitwise
logical operations that can be also applied to the can_dlc field. Because
of a missing check, the CAN drivers may write arbitrary content beyond
the data registers in the CAN controller's I/O memory when processing
can-gw manipulated outgoing frames. This is related to cgw_csum_xor_rel.
An unprivileged user can trigger a system crash (general protection fault)
(CVE-2019-3701).

A flaw was found in the Linux kernel in the function hid_debug_events_read()
in drivers/hid/hid-debug.c file which may enter an infinite loop with
certain parameters passed from a userspace. A local privileged user ('root')
can cause a system lock up and a denial of service (CVE-2019-3819).

In the Linux kernel before 4.20.8, kvm_ioctl_create_device in
virt/kvm/kvm_main.c mishandles reference counting because of a race
condition, leading to a use-after-free (CVE-2019-6974).

A use-after-free vulnerability was found in the way the Linux kernel's KVM
hypervisor emulates a preemption timer for L2 guests when nested (=1)
virtualization is enabled. This high resolution timer(hrtimer) runs when
a L2 guest is active. After VM exit, the sync_vmcs12() timer object is
stopped. The use-after-free occurs if the timer object is freed before
calling sync_vmcs12() routine. A guest user/process could use this flaw
to crash the host kernel ... [Please see the references for more information on the vulnerabilities]");
