How to fix?

Upgrade SLES:15.2 kernel-default-livepatch-devel to version 5.3.18-150200.24.188.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-livepatch-devel package and not the kernel-default-livepatch-devel package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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

netfilter: nftables: exthdr: fix 4-byte stack OOB write

If priv->len is a multiple of 4, then dst[len / 4] can write past the destination array which leads to stack corruption.

This construct is necessary to clean the remainder of the register in case ->len is NOT a multiple of the register size, so make it conditional just like nft_payload.c does.

The bug was added in 4.1 cycle and then copied/inherited when tcp/sctp and ip option support was added.

Bug reported by Zero Day Initiative project (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961).
