Upgrade AlmaLinux:9 perf to version 0:5.14.0-427.13.1.el9_4 or higher.
This issue was patched in ALSA-2024:2394.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

net: tls: fix use-after-free with partial reads and async decrypt

tls_decrypt_sg doesn't take a reference on the pages from clear_skb, so the put_page() in tls_decrypt_done releases them, and we trigger a use-after-free in process_rx_list when we try to read from the partially-read skb.
