Attack-Flow Graph

Executive Summary

This vulnerability allows a local non-privileged user process to improperly process GPU memory, potentially gaining access to sensitive kernel information. It affects specific versions of Arm Ltd's Valhall GPU Kernel Driver and Arm 5th Gen GPU Architecture Kernel Driver.

Impact Analysis

A local attacker could exploit this to read sensitive kernel memory, potentially exposing confidential data or system credentials. This could lead to further system compromise or data breaches.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. Organizations using affected drivers may face compliance violations and potential fines.

Mitigation Strategies

Update the Valhall GPU Kernel Driver and Arm 5th Gen GPU Architecture Kernel Driver to versions beyond the affected ranges (r49p5, r54p3, r55p0). Remove local non-privileged user access to GPU memory processing operations until patches are applied.
