  "description": "In the Linux kernel, the following vulnerability has been resolved:  media: dvb-core: Fix double free in dvb_register_device()  In function dvb_register_device() -\u003E dvb_register_media_device() -\u003E dvb_create_media_entity(), dvb-\u003Eentity is allocated and initialized. If the initialization fails, it frees the dvb-\u003Eentity, and return an error code. The caller takes the error code and handles the error by calling dvb_media_device_free(), which unregisters the entity and frees the field again if it is not NULL. As dvb-\u003Eentity may not NULLed in dvb_create_media_entity() when the allocation of dvbdev-\u003Epad fails, a double free may occur. This may also cause an Use After free in media_device_unregister_entity().  Fix this by storing NULL to dvb-\u003Eentity when it is freed.",
