"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: em28xx: fix use-after-free in em28xx_v4l2_open()\n\nem28xx_v4l2_open() reads dev->v4l2 without holding dev->lock,\ncreating a race with em28xx_v4l2_init()'s error path and\nem28xx_v4l2_fini(), both of which free the em28xx_v4l2 struct\nand set dev->v4l2 to NULL under dev->lock.\n\nThis race leads to two issues:\n - use-after-free in v4l2_fh_init() when accessing vdev->ctrl_handler,\n since the video_device is embedded in the freed em28xx_v4l2 struct.\n - NULL pointer dereference in em28xx_resolution_set() when accessing\n v4l2->norm, since dev->v4l2 has been set to NULL.\n\nFix this by moving the mutex_lock() before the dev->v4l2 read and\nadding a NULL check for dev->v4l2 under the lock."
