How to fix?

Upgrade SLES:15.6 kernel-default-base to version 6.4.0-150600.23.22.1.150600.12.8.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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

bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself

sock_map proto callbacks should never call themselves by design. Protect against bugs like [1] and break out of the recursive loop to avoid a stack overflow in favor of a resource leak.
