AnalysisAIv1 – Sep 15, 2026

An out-of-bounds write reachable through a race condition in google_mba_recv_msg() in google_mba_poll.c allows a locally installed low-privilege application on an affected Android device to corrupt kernel memory and escalate to system/kernel privileges. Rated CVSS 7.0 (AV:L/AC:H/PR:L/UI:N), the flaw requires no user interaction but does need the attacker to already run code on the device and to win a timing window, which keeps it materially below a remote, unauthenticated severity. No public exploit code has been identified and the issue is not listed in CISA KEV at time of analysis; no EPSS score was supplied in the source data.

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.

Race conditions occur when multiple concurrent requests exploit the brief time gap between checking a condition and acting upon it (TOCTOU - Time of Check, Time of Use).
