Amazon Linux 2023: CVE-2022-23222: Important priority package update for kernel

kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types.
A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the kernel/bpf/verifier.c function. In this flaw, a missing sanity check for *_OR_NULL pointer types that perform pointer arithmetic may cause a kernel information leak issue.
