CVE-2016-8480 Linux CVE debrief

Who should care

Android device maintainers, kernel and platform security teams, OEMs shipping the affected kernel branches, and defenders responsible for devices that may run untrusted local apps or have exposed privileged processes.

Technical summary

The vulnerability is described as an elevation of privilege in the Qualcomm Secure Execution Environment Communicator driver. In the supplied record, the impact is kernel-context arbitrary code execution from a local malicious application, with the caveat that the attack path first requires compromising a privileged process. NVD lists CWE-264 and vulnerable CPEs covering Android up to 7.1.1 plus Linux kernel 3.10 and 3.18.

Defensive priority

High for any supported or still-deployed device running the affected Android or kernel branches. The issue is local and requires additional conditions, but successful exploitation can reach kernel context and full system compromise.

Recommended defensive actions

• Apply the Android security bulletin fixes referenced by NVD as soon as they are available for your device build.
• Prioritize patching on devices running Android builds mapped to the vulnerable CPE range and on systems using Linux kernel 3.10 or 3.18.
• Reduce exposure to untrusted local applications and review controls around privileged processes that could be a prerequisite in the attack path.
• Verify OEM and carrier firmware updates, since Android kernel fixes may arrive through vendor-specific build channels.
• Use asset inventory and version detection to identify devices that match the affected Android or kernel branches.
• Monitor for abnormal kernel crashes, privilege boundary violations, or unexpected behavior in processes that bridge app and privileged contexts.

Evidence notes

This debrief is based only on the supplied CVE record, the NVD metadata, and the Android security bulletin referenced by NVD. Timing context uses the CVE published date of 2017-02-08 and modified date of 2026-05-13. NVD metadata supplies CVSS 3.0 AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H, CWE-264, and vulnerable CPEs for Android up to 7.1.1, Linux kernel 3.10, and Linux kernel 3.18. The CVE description states the Qualcomm Secure Execution Environment Communicator driver issue could allow kernel-context arbitrary code execution and that it first requires compromising a privileged process.
