Security readout for executives and security teams
Plain-English summary
CVE-2022-32624 is a MediaTek Android firmware flaw where a buffer size is calculated incorrectly, allowing a local out-of-bounds write. The reported impact is local privilege escalation, with no user interaction required. It is not a remote internet-facing issue in the provided sources.
Executive priority
Handle this as a firmware patch management issue for affected Android fleets. It has serious local impact but no sourced evidence of remote exploitation or active exploitation. Prioritize devices with sensitive access or long patch delays.
Technical view
The issue is in MediaTek throttling logic and maps to CWE-131. Affected chipsets are MT6789, MT6855, MT6895, MT6983, MT8168, MT8365, and MT8781 on Android 11.0 or 12.0. CVSS 3.1 is 6.7: local attack vector, low complexity, high privileges required, no UI, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to Android devices using the listed MediaTek chipsets and affected Android versions. Asset owners usually need OEM model and firmware details to confirm whether the MediaTek patch is present.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. The vulnerability is local, requires high privileges per CVSS, and does not require user interaction. No exploit details are provided in the cited sources.
Researcher notes
Evidence is concise and vendor-centered. The sources identify affected MediaTek chipsets, Android versions, CWE-131, CVSS, and patch identifier, but do not provide detailed root-cause analysis, exploit maturity, or OEM-specific fixed build numbers.
Mitigation direction
- Check MediaTek and device OEM guidance for Patch ID ALPS07405923.
- Apply OEM firmware or Android security updates that include the MediaTek fix.
- Prioritize managed devices with affected MediaTek chipsets on Android 11 or 12.
- Restrict high-privilege local access on affected devices until patched.
Validation and detection
- Inventory Android devices by chipset, model, Android version, and firmware build.
- Confirm whether each OEM build includes MediaTek Patch ID ALPS07405923.
- Review MDM or EDR data for affected Android 11 and 12 devices.
- Track remediation status separately for each OEM firmware branch.

Incorrect Calculation of Buffer Size
Incorrect Calculation of Buffer Size represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
