A use-after-free vulnerability was found in the cyttsp4_core driver in the Linux kernel. This issue occurs in the device

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.
