How to fix?

Upgrade SLES:15.6 kernel-syms-azure to version 6.4.0-150600.8.17.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-syms-azure package and not the kernel-syms-azure 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: Remove tst_run from lwt_seg6local_prog_ops.

The syzbot reported that the lwt_seg6 related BPF ops can be invoked via bpf_test_run() without without entering input_action_end_bpf() first.

Martin KaFai Lau said that self test for BPF_PROG_TYPE_LWT_SEG6LOCAL probably didn't work since it was introduced in commit 04d4b274e2a ("ipv6: sr: Add seg6local action End.BPF"). The reason is that the per-CPU variable seg6_bpf_srh_states::srh is never assigned in the self test case but each BPF function expects it.

Remove test_run for BPF_PROG_TYPE_LWT_SEG6LOCAL.
