AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
Local vector with no user interaction but exploitation demands pre-existing System-level execution, so PR:H applies; only confidentiality is impacted.

In acfw_ffa.c, there is a possible secret read due to a logic error in the code. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
A logic error in the Android kernel's ACFW FF-A (Firmware Framework for Arm A-profile) driver, implemented in acfw_ffa.c, allows a caller already holding System-level execution privileges to read memory that should remain secret, resulting in local information disclosure. Exploitation requires local access and high privileges, needs no user interaction, and affects Android devices carrying the affected kernel build per Google's Pixel security bulletin for September 2026. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete prerequisites: local execution on the Android device, and that the attacking code already holds System-level execution privileges, as stated explicitly in the description and reflected in the CVSS PR:H metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N is internally consistent and matches the description: an attacker needs local execution already at System privilege (PR:H), the logic flaw is deterministic (AC:L), no victim interaction is required, and the outcome is a high-confidentiality, integrity-neutral, availability-neutral read of protected data. … 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 Android security patch level published in Google's Pixel bulletin for 2026-09-01 (https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01), which is the vendor-released fix containing the corrected acfw_ffa.c logic; there is no separately versioned component patch exposed to end users, so remediation is via the monthly system update. … Detailed patch versions, workarounds, and compensating controls in full report. |
