Description

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.

Summary dbcve.org

The Arm Mali GPU kernel driver contains a use-after-free vulnerability where GPU memory operations are mishandled, allowing unprivileged users to access freed memory. This affects Bifrost (r0p0-r38p1, r39p0), Valhall (r19p0-r38p1, r39p0), and Midgard (r4p0-r32p0) GPU generations.

Mitigation

Apply Arm-provided security patches to the Mali GPU kernel driver through firmware/driver updates from the device OEM or OS vendor; prioritize systems with unprivileged user access to the GPU.
