CVE-2022-20581

Local escalation via camera driver use after free

Published Dec 16, 2022 · Updated Apr 18, 2025

Use-after-free in the Pixel camera driver in Google Android kernel allows local users to gain system privileges without user interaction. The driver can access a camera object after it has been freed because of a logic error in its lifetime handling. Exploitation requires local access with high privileges; successful exploitation elevates execution to the System context and can affect confidentiality, integrity, and availability.
