Local information disclosure via improper GPU memory processing
Published Apr 6, 2023 · Updated Feb 12, 2025
Out-of-bounds read in Arm Mali GPU Kernel Driver before r42p0 allows local users to disclose a limited amount of adjacent memory. The driver permits improper GPU memory processing operations to read beyond a buffer boundary, but Arm has not disclosed the specific function or request involved. A non-privileged local account with access to the Mali GPU device is required, and the documented consequence is limited to confidentiality without data modification or service interruption.
