Mali GPU Kernel Driver allows improper GPU memory processing operations

CVE-2023-5643

What is CVE-2023-5643?

The vulnerability identified allows a local non-privileged user to exploit improper GPU memory processing operations within the Bifrost, Valhall, and 5th Gen GPU Kernel Drivers developed by Arm Ltd. If the Mali GPU Kernel Driver is misconfigured and memory is prepared appropriately by the user, there exists a risk of writing to memory segments outside of the designated buffer bounds, potentially leading to unpredictable behavior or system instability. This issue spans multiple versions of the affected drivers, necessitating careful attention to system configurations and updates.
