CVE-2022-49608

In the Linux kernel, the following vulnerability has been resolved: pinctrl: ralink: Check for null return of devm_kcalloc Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.".

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pinctrl: ralink: Verificar el retorno nulo de devm_kcalloc Debido a la posible falla de la asignación, data->domains podría ser un puntero NULL y provocará la desreferencia del puntero NULL más adelante. Por lo tanto, podría ser mejor verificarlo y devolver directamente -ENOMEM sin liberar los datos manualmente si falla, porque el comentario de devm_kmalloc() dice "La memoria asignada con esta función se libera automáticamente al desconectar el controlador".
