the following security issues:

KVM: x86/mmu: fix NULL pointer dereference on guest INVPCID
(CVE-2022-1789).

KVM: x86: avoid calling x86 emulator without a decoded instruction
(CVE-2022-1852).

A use-after-free vulnerability was found in the Linux kernel's Netfilter
subsystem in net/netfilter/nf_tables_api.c. This flaw allows a local
attacker with user access to cause a privilege escalation issue
(CVE-2022-1966).

An out-of-bound write vulnerability was identified within the netfilter
subsystem which can be exploited to achieve privilege escalation to
root. In order to trigger the issue it requires the ability to create
user/net namespaces (CVE-2022-1972).

fs/ntfs3: Fix invalid free in log_replay (CVE-2022-1973).

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