Detailsinfo

A vulnerability, which was classified as critical, was found in Arm Bifrost GPU Kernel Driver, Valhall GPU Kernel Driver and 5th Gen GPU Architecture Kernel Driver up to r45p0 (Hardware Driver Software). This affects some unknown functionality. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared 02/05/2024. The advisory is shared at developer.arm.com. This vulnerability is uniquely identified as CVE-2023-5643 since 10/18/2023. Neither technical details nor an exploit are publicly available.

Upgrading to version r46p0 eliminates this vulnerability.
