When pvr2_hdw_create returns back to pvr2_context_create,\nit calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,\nwhich leads to that pvr2_hdw_destroy directly returns.\n\nFix this by adding v4l2_device_unregister to decrease the refcount of\nusb interface."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: pvrusb2: se corrige una fuga de memoria en pvr_probe.
