x86: KVM: SVM: always update the x2avic msr interception (CVE-2023-5090)

A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation.

If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer.

We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times.

We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630. (CVE-2023-6111)
