CVE-2022-38181
Arm Mali GPU Kernel Driver Use-After-Free Vulnerability
What it is
The Arm Mali GPU kernel driver allows unprivileged users to access freed memory because GPU memory operations are mishandled. This affects Bifrost r0p0 through r38p1, and r39p0; Valhall r19p0 through r38p1, and r39p0; and Midgard r4p0 through r32p0.
CISA: Arm Mali GPU Kernel Driver contains a use-after-free vulnerability that may allow a non-privileged user to gain root privilege and/or disclose information.
What to do
Apply updates per vendor instructions.
