CVE-2023-26083: Memory leak vulnerability in Mali GPU Kernel Driver in Midgard GPU Kernel Driver all versions from r6p0 - r32p0, Bifrost GPU Kernel Driver a
Noroxi assessment
Priority: Plan (action score 43/100)
- CISA has confirmed exploitation in the wild (Apr 7, 2023). Remediation deadline for US federal agencies: Apr 28, 2023.
- Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 68.6% of all records.
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
