Descriptions

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema de sonido del kernel de Linux en la forma en que un usuario desencadena las llamadas concurrentes de PCM hw_params. La ioctls hw_free o una condición de carrera similar ocurre dentro de ALSA PCM para otras ioctls. Este defecto permite a un usuario local bloquear o potencialmente escalar sus privilegios en el sistema
