NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_55_7-default package and not the kernel-livepatch-5_14_21-150500_55_7-default package as distributed by SLES. See How to fix? for SLES:15.5 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.
