Lifecycle Timeline
1DescriptionNVD
A local non-privileged user can make improper GPU memory processing operations. If the operations are carefully prepared, then they could be used to gain access to already freed memory.
AnalysisAI
A local non-privileged user can make improper GPU memory processing operations. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. A local non-privileged user can make improper GPU memory processing operations. If the operations are carefully prepared, then they could be used to gain access to already freed memory. Affected products include: Arm Valhall Gpu Kernel Driver.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Use memory-safe languages or bounds-checking. Enable ASLR, DEP/NX, stack canaries. Use safe string functions.
