Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Local, sandboxed app context drives AV:L and PR:L; the missing bounds check is trivially triggerable (AC:L) and leaks memory only, so C:H/I:N/A:N.

In ReadDataElement of common.c, there is a possible information disclosure due to an incorrect bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
An out-of-bounds read in ReadDataElement (common.c) within the Android platform allows a locally installed application to disclose sensitive memory contents without any additional execution privileges or user interaction. The flaw is a missing/incorrect bounds check on an attacker-influenced length or index value, rated CVSS 5.5 (AV:L/AC:L/PR:L/UI:N, C:H/I:N/A:N), so the practical impact is confidentiality loss rather than code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to run code as a low-privileged local application on the Android device (CVSS PR:L/AV:L) and to pass attacker-controlled data into the parsing path that reaches ReadDataElement in common.c - typically via the component's exposed interface or a crafted file format handled by that code. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector is deliberately modest at 5.5: AV:L/PR:L/UI:N means an attacker must already have code executing on the device, albeit from an ordinary unprivileged app, with no user interaction needed. … 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 | The primary fix is the vendor patch shipped in the Android/Pixel September 2026 security bulletin (https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01) - apply it via OTA and require a security patch level of 2026-09-01 or later on managed devices. … Detailed patch versions, workarounds, and compensating controls in full report. |
