AnalysisAIv1 – Sep 15, 2026

Local privilege escalation in the Android kernel's Arm SMMUv3 driver (arm-smmu-v3.c) allows an attacker holding a low-privileged local context to subvert the IOMMU's protection mechanism and reach kernel-level access on a vulnerable device. The flaw is a logic error affecting multiple functions of the driver, rated CVSS 7.8 with a local attack vector, low privileges, and no user interaction required. Google ships the fix in the September 2026 Pixel/Android security bulletin; no CISA KEV listing and no public exploit code were identified at the time of analysis.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
