CVE-2024-3655

Freed GPU memory access via improper processing

Published Sep 3, 2024 · Updated Sep 30, 2024

Use-after-free in Arm Mali GPU Kernel Drivers r43p0 through r49p0 allows local users to access previously freed GPU memory. Arm has disclosed only that improper GPU memory processing retains access after memory is freed; no file, function, or exact trigger is public. A local non-privileged user must be able to submit GPU operations, exposing freed contents and risking modification or service interruption.
