  - An issue was discovered in drivers/media/platform/vivid     in the Linux kernel through 5.3.8. It is exploitable     for privilege escalation on some Linux distributions     where local users have /dev/video0 access, but only if     the driver happens to be loaded. There are multiple     race conditions during streaming stopping in this     driver (part of the V4L2 subsystem). These issues are     caused by wrong mutex locking in     vivid_stop_generating_vid_cap(),     vivid_stop_generating_vid_out(),     sdr_cap_stop_streaming(), and the corresponding     kthreads. At least one of these race conditions leads     to a use-after-free.(CVE-2019-18683)
