How to fix?

Upgrade SLES:15.4 kernel-devel to version 5.14.21-150400.24.111.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the dst array. On each iteration, 8 bytes are written, but dst is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.
