Summary

This kernel-linus update is based on upstream 5.15.18 and fixes atleast the following security issues:
A random memory access flaw was found in the Linux kernels GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system (CVE-2022-0330).
A use-after-free flaw was found in the Linux kernels vmw_execbuf_copy_fence_user function in drivers/gpu/drm/vmwgfx/ vmwgfx_execbuf.c in vmwgfx. This flaw allows a local attacker with user privileges to cause a privilege escalation problem (CVE-2022-22942).
For other upstream fixes, see the referenced changelogs.
