Alert meAnalysisAIv1 – Sep 15, 2026
Local privilege escalation in Android's Bluetooth stack allows an attacker who already holds System-level execution on a device to turn a race condition in bluetooth_cco.cc into a use-after-free and elevate to a more privileged context. Google device users on builds prior to the September 2026 Pixel bulletin (patch level 2026-09-01) are the affected population, and the flaw requires no user interaction, though attack complexity is high and System privileges are a prerequisite. No public exploit code has been identified and the issue is not listed as actively exploited, so real-world risk concentrates in targeted or chained attacks against already-compromised high-value devices.

In multiple functions of bluetooth_cco.cc, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

SSVC AssessmentENISA
Priority Score
Attack Technique
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
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).
