NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150400_24_84-default package and not the kernel-livepatch-5_14_21-150400_24_84-default package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A use-after-free vulnerability was found in the cyttsp4_core driver in the Linux kernel. This issue occurs in the device cleanup routine due to a possible rearming of the watchdog_timer from the workqueue. This could allow a local user to crash the system, causing a denial of service.
