In the Linux kernel, the following vulnerability has been resolved:

media: uvcvideo: Return queued buffers on start_streaming() failure

Return buffers if streaming fails to start due to uvc_pm_get() error.

This bug may be responsible for a warning I got running

while :; do yavta -c3 /dev/video0; done

on an xHCI controller which failed under this workload. I had no luck reproducing this warning again to confirm.
