CVE-2024-35874

  2. Vulnerabilities (CVE)
  3. CVE-2024-35874
In the Linux kernel, the following vulnerability has been resolved: aio: Fix null ptr deref in aio_complete() wakeup list_del_init_careful() needs to be the last access to the wait queue entry - it effectively unlocks access. Previously, finish_wait() would see the empty list head and skip taking the lock, and then we'd return - but the completion path would still attempt to do the wakeup after the task_struct pointer had been overwritten.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: aio: corrige el ptr deref null en aio_complete() wakeup list_del_init_careful() debe ser el último acceso a la entrada de la cola de espera; efectivamente desbloquea el acceso. Anteriormente, Finish_wait() veía el encabezado de la lista vacía y omitía tomar el bloqueo, y luego regresabamos, pero la ruta de finalización aún intentaría realizar la reactivación después de que se hubiera sobrescrito el puntero task_struct.
