  "details": "In the Linux kernel, the following vulnerability has been resolved:  media: em28xx: fix use-after-free in em28xx_v4l2_open()  em28xx_v4l2_open() reads dev-\u003ev4l2 without holding dev-\u003elock, creating a race with em28xx_v4l2_init()'s error path and em28xx_v4l2_fini(), both of which free the em28xx_v4l2 struct and set dev-\u003ev4l2 to NULL under dev-\u003elock.  This race leads to two issues:  - use-after-free in v4l2_fh_init() when accessing vdev-\u003ectrl_handler,    since the video_device is embedded in the freed em28xx_v4l2 struct.  - NULL pointer dereference in em28xx_resolution_set() when accessing    v4l2-\u003enorm, since dev-\u003ev4l2 has been set to NULL.  Fix this by moving the mutex_lock() before the dev-\u003ev4l2 read and adding a NULL check for dev-\u003ev4l2 under the lock.",
