Recommended response

Check inventory. Check lockfiles and deployed manifests for Linux/Linux.
Review the reported fix. Update Linux/Linux to 97adc8cd04df2085f7fd437838005f3bb16bafae if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: media: video-i2c: use vb2_video_unregister_device on driver removal The driver uses vb2_fop_release() as its file release operation, so vb2_video_unregister_device() should be used instead of video_unregister_device() during driver removal. This ensures that the vb2 queue is properly disconnected before the video device is unregistered.
