AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Local malicious app (AV:L, PR:L) abuses a missing permission check with no interaction (UI:N); arbitrary privileged package install yields full C/I/A impact.

In the Setup Wizard, there is a possible remote package install due to a missing permission check. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

AnalysisAI
Privilege escalation in the Android Setup Wizard (Google Android, fixed in the September 2026 Pixel bulletin) lets a locally-running, low-privilege app trigger a package installation because the Setup Wizard's install code path performs a missing permission check. Per the assessed vector CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, exploitation requires code already executing on the device under a low-privileged context, needs no user interaction and no additional execution privileges, and yields high confidentiality and integrity impact in a local attack. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a locally-present, low-privilege application on the device (PR:L) that can reach the Setup Wizard's package-install code path lacking the permission check (CWE-693). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H = 7.8 HIGH) describes a LOCAL, low-privilege escalation of privilege - not a remote attack. … 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 by installing the Android security update containing the September 2026 Pixel bulletin fixes (Google Android Security Bulletin, Pixel, 2026-09-01, https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01); on Pixel hardware this arrives as the monthly over-the-air update, and Patch availability is confirmed via vendor advisory, though no specific build or fix version string is provided in the supplied data, so verify the device reports a security patch level of 2026-09-01 or later under Settings > About phone. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory Android/Pixel devices and confirm exposure, especially where low-privilege apps are installed; enforce MDM policies that block installation from unknown sources and review app allowlists. …
