CVE-2020-11151

Memory corruption via concurrent video ioctls

Published Jan 21, 2021 · Updated Aug 4, 2024

Use-after-free in Qualcomm Snapdragon video components allows local users with high privileges to cause unspecified impact via concurrent ioctls. Two threads can invoke a user-space ioctl concurrently, and inadequate synchronization permits video memory to be freed while it remains in use. Exploitation requires local high privileges and winning the race; Qualcomm has not published a more specific consequence.
