How to fix?

Upgrade SLES:15.3 ocfs2-kmp-default to version 5.3.18-150300.59.161.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ocfs2-kmp-default package and not the ocfs2-kmp-default package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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

net/sched: act_mirred: don't override retval if we already lost the skb

If we're redirecting the skb, and haven't called tcf_mirred_forward(), yet, we need to tell the core to drop the skb by setting the retcode to SHOT. If we have called tcf_mirred_forward(), however, the skb is out of our hands and returning SHOT will lead to UaF.

Move the retval override to the error path which actually need it.
