Upgrade AlmaLinux:9 perf to version 0:5.14.0-162.22.2.el9_1 or higher.
This issue was patched in ALSA-2023:1470.
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.
A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.
