AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
Local access (AV:L) with System-level privileges already required (PR:H); no user interaction; out-of-bounds read yields confidentiality loss only (C:H, I:N, A:N).

In do_sss_aes_gcm_256_op of crypto-aes.c, there is a possible out-of-bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
An out-of-bounds read in the AES-GCM-256 crypto implementation of the Android kernel (function do_sss_aes_gcm_256_op in crypto-aes.c) allows disclosure of memory contents to code that is already running at System privilege on an affected device. The flaw is a missing bounds check on an input length or index (CWE-120 class buffer handling error), rated 4.4 (Medium) with the vector CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N, meaning exploitation is local and requires the attacker to already hold System (PR:H) execution privileges; no user interaction is needed once that position is held. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already possess System execution privileges (PR:H) and local access (AV:L) on the affected Android/Pixel device, then reach the do_sss_aes_gcm_256_op AES-GCM-256 crypto code path in crypto-aes.c that lacks a bounds check. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-priority issue despite the CRITICAL-sounding CWE-120/'Buffer Overflow' tag, and the vendor CVSS of 4.4 (Medium) is well-calibrated. … 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 fix published in the September 2026 Android/Pixel Security Bulletin (https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01, cross-referenced at https://nvd.nist.gov/vuln/detail/CVE-2026-0177); the input data does not specify an exact patched build or patch-level string, so treated as 'patch available per vendor advisory' and the precise build identifier should be confirmed on the bulletin page before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
