How to fix?

Upgrade SLES:15.3 kernel-default-livepatch to version 5.3.18-150300.59.118.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-livepatch package and not the kernel-default-livepatch package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness, potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field that overlaps with rec->tx_ready.
