CVE-2023-28466 Open this link in a new tabHow to fix?
Upgrade Amazon-Linux:2 kernel to version 0:4.14.318-240.529.amzn2 or higher.
This issue was patched in ALAS2-2023-2100.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2 relevant fixed versions and status.
do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).
