Description Preview

A memory leak vulnerability (CWE-401) has been identified in multiple ARM Mali GPU Kernel Drivers, including Midgard (r6p0-r32p0), Bifrost (r0p0-r42p0), Valhall (r19p0-r42p0), and Avalon (r41p0-r42p0). This vulnerability allows non-privileged users to execute valid GPU processing operations that can expose sensitive kernel metadata. The issue could potentially lead to information disclosure and may be leveraged as part of a more complex attack chain.

Overview

The vulnerability affects ARM's Mali GPU Kernel Drivers across multiple generations of their graphics processing architecture. The memory leak occurs when a non-privileged user performs specific GPU operations, which then fail to properly release allocated memory resources. This results in the potential exposure of sensitive kernel metadata that should remain protected. The vulnerability is classified as CWE-401 (Memory Leak), which can lead to resource exhaustion over time and potential information disclosure. Affected systems include mobile devices, tablets, smart TVs, and other embedded systems that utilize ARM Mali GPUs with the vulnerable driver versions.

Remediation

Organizations and users should implement the following remediation steps:

  1. Update to the latest Mali GPU driver version provided by ARM or your device manufacturer that addresses this vulnerability.
  2. If updates are not immediately available, consider implementing access controls to limit which applications can access GPU functionality.
  3. Monitor system resources for unusual memory consumption patterns that could indicate exploitation attempts.
  4. Device manufacturers should integrate the patched drivers into their firmware updates and distribute them to end users.
  5. End users should ensure their devices are configured to receive and install security updates automatically.
