Security readout for executives and security teams
Plain-English summary
CVE-2022-32631 is a MediaTek Wi-Fi flaw that could let an attacker already operating locally with high privileges corrupt memory and escalate impact on affected devices. It is not described as remotely exploitable, and the provided sources do not show active exploitation.
Executive priority
Treat this as a moderate remediation item for affected device fleets. It is not currently source-supported as actively exploited, but the impact is high if reachable in a local privilege chain on unpatched MediaTek-based devices.
Technical view
The issue is an out-of-bounds write in the Wi-Fi component caused by improper input validation, mapped to CWE-787. CVSS 3.1 is 6.7 with local attack vector, low complexity, high privileges required, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to devices using the listed MediaTek chipsets running Android 11.0, 12.0, 13.0, or Yocto 3.1. Actual risk depends on OEM firmware integration and whether the MediaTek December 2022 security fix is present.
Exploitation context
The source bundle does not cite public exploitation, proof-of-concept availability, or CISA KEV listing. The CVSS vector indicates local access with high privileges is required, so this is more relevant to chained compromise scenarios than initial intrusion.
Researcher notes
Evidence is sparse: the bundle provides affected chipsets, OS versions, CVSS, CWE-787, and MediaTek patch ID, but no technical root-cause detail, vulnerable function, exploit conditions beyond CVSS, or fixed firmware version mapping.
Mitigation direction
- Check MediaTek and OEM guidance for patch ALPS07453613.
- Apply firmware or security updates that include the December 2022 MediaTek fix.
- Inventory devices using the affected MediaTek chipsets and listed OS versions.
- Prioritize updates for managed Android, embedded, and fleet devices with sensitive access.
Validation and detection
- Confirm device chipset against the affected MediaTek product list.
- Confirm OS version is Android 11.0, 12.0, 13.0, or Yocto 3.1.
- Verify OEM firmware includes MediaTek patch ID ALPS07453613.
- Check vulnerability scanners or SBOM data for CVE-2022-32631 coverage.

Out-of-bounds Write
Out-of-bounds Write represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
