En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:

drm/amdgpu: Corrige la fuga de runtime PM en amdgpu_debugfs_test_ib_show()

amdgpu_debugfs_test_ib_show() reanuda el dispositivo con pm_runtime_get_sync() antes de tomar el semáforo del dominio de reinicio con down_write_killable(). Si la adquisición del bloqueo de escritura se interrumpe, la función retorna sin llamar a pm_runtime_put_autosuspend(), lo que provoca una fuga de la referencia de runtime PM adquirida para el dispositivo y mantiene la GPU activa.

Suelte la referencia de runtime PM en la ruta de error de down_write_killable() interrumpido antes de retornar.
