Severity by source
AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Local kernel race requiring pre-existing System privileges, so PR:H and AV:L, with timing-sensitive exploitation raising AC to H; full C/I/A impact to the kernel.
Primary rating from Vendor (Google_Devices).

In multiple locations, there is a possible time-of-check to time-of-use 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.
AnalysisAI
A time-of-check to time-of-use (TOCTOU) race condition in multiple locations of the Android kernel allows an attacker who already holds System-level execution privileges on a device to win a timing window and escalate to higher (kernel/root) privileges, with no user interaction required. The flaw is rated CVSS 6.7 (AV:L/AC:L/PR:H/UI:N) and is fixed through the September 2026 Android Security Bulletin for Pixel devices. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local execution on the target Android device with code already running in the System privilege context (CVSS PR:H), plus the ability to invoke the affected kernel interface and spawn or control a concurrent thread to race the check window; the vulnerability sits in kernel components shared across multiple code locations, so the precise callable interface must be confirmed from the corresponding AOSP kernel patch rather than assumed from the bulletin. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.7 with AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H describes a local, low-complexity attack that requires the attacker to already hold System-level privileges, but which then yields high confidentiality, integrity, and availability impact - a post-exploitation escalation rather than an initial access vector. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the September 2026 Android Security Bulletin update for Pixel devices, referenced at https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01, and verify the device reports the September 2026 (or later) security patch level; non-Pixel OEMs should be tracked for their equivalent kernel builds since no standalone fix version is published in the supplied data. … Detailed patch versions, workarounds, and compensating controls in full report. |
