AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Local integer-overflow permission bypass needing pre-existing System privileges (PR:H, AV:L), no UI; I retain C/I/A:H to match vendor though the marginal gain over System is modest.

In multiple locations, there is a possible permission bypass due to an integer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Permission bypass in the Android kernel, caused by an integer overflow in multiple code locations, allows an actor who already holds Android System execution privileges on a Pixel device to escalate privileges locally with no user interaction required. The vendor scores it 6.7 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), and the PR:H prerequisite is the decisive constraint: the high confidentiality, integrity and availability metrics describe what a System-context actor can reach, not what an ordinary installed app or remote attacker can achieve. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already possess Android System execution privileges (PR:H) and local access (AV:L) to the device; the description explicitly states 'System execution privileges needed.' No user interaction is required (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-priority issue despite the 'High' impact metrics in the vendor CVSS. … 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 vendor fix documented in the September 2026 Pixel security bulletin at https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01 - this is a Patch available per vendor advisory situation, meaning the bulletin is the source of record for the exact Pixel build and patch level that resolves the integer overflow, and no independent fix version is stated in the supplied data. … Detailed patch versions, workarounds, and compensating controls in full report. |
