      "title": "media: zoran: Avoid freeing a registered video_device twice",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: zoran: Avoid freeing a registered video_device twice\n\nzoran_init_video_device() installs zoran_vdev_release() as the\nvideo_device release callback through zoran_template. After\nvideo_register_device() succeeds, video_unregister_device() drops the\nregistered video_device reference and the V4L2 core eventually invokes\nthat release callback, which kfree()s the video_device.\n\nzoran_exit_video_devices() called video_unregister_device() and then\nkfree(zr->video_dev), so device teardown could free the same\nvideo_device twice.\n\nRemove the direct kfree() and clear the cached pointer after\nunregistering. The pre-registration failure path keeps its manual free\nbecause the video_device was not registered there.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.",
