NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source-azure package and not the kernel-source-azure package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating skb_shared_info in the userspace, which is exploitable in systems without SMAP protection since skb_shared_info contains references to function pointers.
