CVE-2022-36449Public exploit

Kernel memory access via improper GPU operations

Published Sep 1, 2022 · Updated Aug 3, 2024

Memory-safety flaws in Arm Mali GPU Kernel Driver releases allow local users to access freed pages, corrupt memory, or disclose mappings. The five grouped issues retain CPU or GPU access to released physical pages, free page tables before removing referencing PTEs and flushing them, expose physical addresses, and omit a CSF VFS read-buffer size check. With native code in an unprivileged app context, attackers can reuse released pages as page tables to cross Android's permissions boundary and gain broad access to user data.
