How to fix?

Upgrade SLES:15.5 kernel-zfcpdump to version 5.14.21-150500.55.73.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump package and not the kernel-zfcpdump package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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

ila: block BH in ila_output()

As explained in commit 1378817486d6 ("tipc: block BH before using dst_cache"), net/core/dst_cache.c helpers need to be called with BH disabled.

ila_output() is called from lwtunnel_output() possibly from process context, and under rcu_read_lock().

We might be interrupted by a softirq, re-enter ila_output() and corrupt dst_cache data structures.

Fix the race by using local_bh_disable().
