CVE-2023-4134

Se encontró una vulnerabilidad de use-after-free en el controlador cyttsp4_core del kernel de Linux. Este problema se produce en la rutina de limpieza del dispositivo debido a un posible rearme del watchdog_timer desde la cola de trabajo. Esto podría permitir que un usuario local bloquee el sistema, lo que provocaría una denegación de servicio.

A local attacker could possibly use this to cause a denial of service. It was discovered that a race condition existed in the Cypress touchscreen driver in the Linux kernel during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.
