CVE-2024-39282

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: Fix FSM command timeout issue When driver processes the internal state change command, it use an asynchronous thread to process the command operation. If the main thread detects that the task has timed out, the asynchronous thread will panic when executing the completion notification because the main thread completion object has been released.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: wwan: t7xx: Solución del problema de tiempo de espera del comando FSM Cuando el controlador procesa el comando de cambio de estado interno, utiliza un hilo asincrónico para procesar la operación del comando. Si el hilo principal detecta que se agotó el tiempo de espera de la tarea, el hilo asincrónico entrará en pánico al ejecutar la notificación de finalización porque se liberó el objeto de finalización del hilo principal.
