Severity by source
AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Local trigger with no UI (AV:L/UI:N); attacker must already hold System privileges so PR:H; image-auth bypass plausibly yields full C/I/A within the same scope (S:U).

In gsa_sw_pk_hash_compare of image-auth-srv.c, there is a possible escalation of privilege due to a logic error in the code. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in Google Android's image authentication service (image-auth-srv.c) allows a component that already holds System execution privileges to abuse a logic error in the gsa_sw_pk_hash_compare public-key hash-comparison routine, achieving escalation into a more trusted execution context. The flaw is reachable only locally (AV:L) and requires high privileges (PR:H) with no user interaction (UI:N), so it is not an initial-access or remote vector. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution already holding System execution privileges (PR:H) on an affected Android/Pixel device - no user interaction is needed (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All exploitability signals point to a low-urgency, defense-in-depth issue rather than an active priority. … 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 distributed through Google's Pixel security bulletin for 2026-09-01 (https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01); this is the authoritative remediation channel and the relevant patch level should be confirmed against the device build fingerprint. … Detailed patch versions, workarounds, and compensating controls in full report. |
