Description
A memory leak exists in the Mali GPU Kernel Driver, specifically within the Midgard, Bifrost, Valhall, and Avalon GPU Kernel Drivers. This issue allows a non-privileged user to perform valid GPU processing operations that expose sensitive kernel metadata. The vulnerability involves a kernel address disclosure in the Mali GPU drivers, where raw kernel pointers are logged into a timeline stream ring buffer. This detail expands the attack surface and may lead to similar issues in other areas. The issue has been exploited in the wild, and reports indicate that a previous attempt to address the issue was improper. There is no information available regarding the number of affected devices.
