DescriptionNVD

A local non-privileged user can make improper GPU processing operations to access a limited amount outside of buffer bounds or to exploit a software race condition. If the system’s memory is carefully prepared by the user, then this in turn could give them access to already freed memory

AnalysisAI

A local non-privileged user can make improper GPU processing operations to access a limited amount outside of buffer bounds or to exploit a software race condition. Rated medium severity (CVSS 4.7). No vendor patch available.

Technical ContextAI

This vulnerability is classified as Use After Free (CWE-416), which allows attackers to access freed memory to execute arbitrary code or crash the application. A local non-privileged user can make improper GPU processing operations to access a limited amount outside of buffer bounds or to exploit a software race condition. If the system’s memory is carefully prepared by the user, then this in turn could give them access to already freed memory Affected products include: Arm Mali Gpu Kernel Driver, Arm Valhall Gpu Kernel Driver.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Use smart pointers or garbage-collected languages. Set pointers to NULL after freeing. Enable memory sanitizers.
