CVE-2022-32630: In throttling, there is a possible out of bounds write due to an incorrect calculation of buffer size.

In throttling, there is a possible out of bounds write due to an incorrect calculation of buffer size. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07405966; Issue ID: ALPS07405966.

Security readout for executives and security teams

Plain-English summary

CVE-2022-32630 is a MediaTek Android vulnerability in throttling logic. An incorrect buffer-size calculation can cause an out-of-bounds write. The business impact is mainly privilege escalation on affected devices, but exploitation is local and requires high privileges, reducing broad remote risk.

Executive priority

Treat this as a targeted device hygiene issue, not an internet-facing emergency. Prioritize patch verification for fleets with affected MediaTek Android devices, especially where devices handle sensitive data or run privileged enterprise agents.

Technical view

The flaw is classified as CWE-131 and affects MediaTek MT6789, MT6855, MT6895, MT6983, and MT8781 on Android 12.0 and 13.0. CVSS 3.1 is 6.7: local attack vector, low complexity, high privileges required, no user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is most likely in Android devices using the listed MediaTek chipsets and Android 12 or 13 builds that lack the MediaTek December 2022 security update containing patch ALPS07405966.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation is described as local, requires high privileges, and does not require user interaction. No public exploit status is provided in the cited sources.

Researcher notes

Evidence is limited to the CVE record and MediaTek bulletin reference. The key technical condition is an out-of-bounds write caused by incorrect buffer-size calculation in throttling. Avoid assuming exploitability beyond the stated local, high-privilege CVSS conditions.

Mitigation direction

  • Check OEM firmware guidance for affected MediaTek-based Android devices.
  • Apply updates containing MediaTek patch ID ALPS07405966 where available.
  • Prioritize managed Android 12 and 13 devices with listed chipsets.
  • Restrict high-privilege local access on unpatched devices.
  • Monitor MediaTek and OEM bulletins for replacement or backported fixes.

Validation and detection

  • Inventory Android devices for listed MediaTek chipsets and OS versions.
  • Compare device patch levels against OEM December 2022 or later advisories.
  • Confirm whether firmware includes patch ID ALPS07405966.
  • Track exceptions for devices without available vendor updates.
  • Review EDR or MDM telemetry for unusual privileged local activity.
