An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Midgard r0p0 through r32p0, Bifrost r0p0 through r41p0 before r42p0, Valhall r19p0 through r41p0 before r42p0, and Avalon r41p0 before r42p0.

Out-of-bounds Write vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user to make improper GPU memory processing operations. Depending on the configuration of the Mali GPU Kernel Driver, and if the system’s memory is carefully prepared by the user, then this in turn could write to memory outside of buffer bounds.This issue affects Bifrost GPU Kernel Driver: from r41p0 through r45p0; Valhall GPU Kernel Driver: from r41p0 through r45p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r45p0.

Remedy

This issue is fixed in Bifrost, Valhall, and Arm 5th Gen GPU Architecture Kernel Driver r46p0. Users are recommended to upgrade if they are impacted by this issue.
