  script_tag(name:"insight", value:"This kernel-linus update is based on upstream 5.15.82 and fixes at least the
following security issues:

A flaw was found in the Linux kernel. A denial of service flaw may occur
if there is a consecutive request of the NVME_IOCTL_RESET and the
NVME_IOCTL_SUBSYS_RESET through the device file of the driver, resulting
in a PCIe link disconnect (CVE-2022-3169).

A flaw was found in the KVM's AMD nested virtualization (SVM). A malicious
L1 guest could purposely fail to intercept the shutdown of a cooperative
nested guest (L2), possibly leading to a page fault and kernel panic in
the host (L0) (CVE-2022-3344).

A vulnerability has been found in Linux Kernel function kcm_tx_work of the
file net/kcm/kcmsock.c of the component kcm. The manipulation leads to race
condition (CVE-2022-3521).

An incorrect TLB flush issue was found in the Linux kernel's GPU i915 kernel
driver, potentially leading to random memory corruption or data leaks. This
flaw could allow a local user to crash the system or escalate their
privileges on the system (CVE-2022-4139).

A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in
how a user changes certain kernel parameters and variables. This flaw
allows a local user to crash or potentially escalate their privileges on the
system (CVE-2022-4378).

A race condition in the x86 KVM subsystem in the Linux kernel allows guest
OS users to cause a denial of service (host OS crash or host OS memory
corruption) when nested virtualisation and the TDP MMU are enabled
(CVE-2022-45869).

For other upstream fixes in this update, see the referenced changelogs.");
