AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Local unprivileged app (AV:L/PR:N/UI:N) exploiting a kernel logic error to escalate privilege; I retain C/I/A:H per vendor though it is generous for an unspecified permission bypass.
Primary rating from Vendor (Google_Devices).

Lifecycle Timeline
9DescriptionCVE.org
In enable_segment of remap.c, there is a possible permission bypass due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in the Android kernel's remap.c enable_segment path allows an unprivileged app to bypass segment permissions and gain elevated privileges on affected Pixel and Android devices (CVSS 8.4, High). Exploitation requires only an app-level foothold with no user interaction, and no public exploit code has been identified at time of analysis; EPSS is low at 0.13% (3rd percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires local code execution as an unprivileged app on an affected Android/Pixel device (AV:L, PR:N, UI:N), which then reaches the enable_segment function in remap.c to trigger the permission-bypass logic error; no authentication, user interaction, or special device configuration is stated as required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 3.1 vector AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H yields vendor base 8.4 (High), and the metrics are internally consistent with the description: a local, low-complexity permission-bypass logic error that a fully unprivileged app can trigger with no user interaction (PR:N/UI:N). … 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-released patch by updating to the Android 2026-09-01 security patch level from the Pixel bulletin at https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01; devices at that patch level or later are fixed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, confirm which Pixel and Android devices in the managed fleet are below the 2026-09-01 patch level and flag any that are enrolled in BYOD or unmanaged programs, since those represent the largest unaddressed population; notify device owners and IT service desk that an Android Security Bulletin fix (2026-09-01 patch level) addresses a kernel privilege escalation and that update deferrals should be lifted. …
