[ALAS-2023-1883] Amazon Linux AMI 2014.03 - ALAS-2023-1883: important priority package update for kernel

Package updates are available for Amazon Linux AMI that fix the following vulnerabilities:
CVE-2023-5717:
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-2023-34324:
A flaw in the kernel Xen event handler can cause a deadlock with Xen console handling in unprivileged Xen guests.

CVE-2023-3397:
A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can lead to a use-after-free vulnerability and crash.
