AnalysisAIv1 – Sep 15, 2026

An integer overflow in the Android VPU (video processing unit) driver's size handling leads to an out-of-bounds write in kernel memory, allowing a locally installed application to escalate privileges to kernel/system level on affected Pixel devices. Exploitation requires only local low-privileged access (CVSS:3.1/AV:L/AC:L/PR:L/UI:N) and no user interaction, making it attractive for a malicious or trojanized app. No public exploit code or CISA KEV listing was identified at time of analysis, and the EPSS signal is not provided; the vulnerability is addressed in the September 2026 Android/Pixel security bulletin.

DescriptionCVE.org

In VPU, there is a possible out-of-bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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.

Attack Technique

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
