Kernel metadata disclosure via GPU memory leak
Published Apr 6, 2023 · Updated Oct 21, 2025
Information disclosure in Arm Mali GPU Kernel Driver versions listed below allows local users to expose sensitive kernel metadata through valid GPU processing operations. The disclosed record identifies a memory leak in the Midgard, Bifrost, Valhall, and Avalon kernel-driver families but does not publish a function or buffer-level locus. A non-privileged local user must be able to submit GPU work; the stated consequence is kernel-metadata disclosure rather than modification or service interruption.
