NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_13_18-rt package and not the kernel-livepatch-5_14_21-150500_13_18-rt package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A local user could use this flaw to crash the system or potentially cause a denial of service.
