CVE-2024-1067

Cross-process memory access via GPU use-after-free

Published May 3, 2024 · Updated Mar 27, 2025

Use-after-free in Arm Mali GPU kernel drivers r41p0 through r47p0 allows local users to affect another process's memory. Arm has not disclosed the precise allocation and freeing locus; crafted GPU memory operations reuse freed storage under affected driver configurations. Exposure requires an Armv8.0 core and a susceptible Linux kernel and Mali driver combination, enabling cross-process memory effects.
