Vulnerability details

The vulnerability allows a local user to potentially cause a denial of service by interacting with a video device during driver removal.

The vulnerability exists due to improper resource lifecycle management in the Linux kernel video-i2c driver when unregistering a video device without first disconnecting its videobuf2 queue. A local user can use a video device across driver removal to potentially disrupt kernel operation through access to a queue that has not been properly disconnected.
