CVE-2022-32626: In display, there is a possible out of bounds write due to an incorrect bounds check.

In display, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07326239; Issue ID: ALPS07326239.

Security readout for executives and security teams

Plain-English summary

CVE-2022-32626 is a MediaTek display component memory corruption flaw. On affected Android 11 or 12 devices, a local actor with high privileges could trigger an out-of-bounds write and potentially gain broader system-level impact. It is not remotely exploitable based on the provided CVSS data.

Executive priority

Treat this as a device fleet hygiene issue rather than an emergency internet-facing incident. Prioritize patch verification for managed Android devices with affected MediaTek chipsets, especially where devices handle sensitive data or remain on older OEM firmware.

Technical view

The issue is CWE-787 out-of-bounds write in MediaTek display code caused by an incorrect bounds check. CVSS 3.1 is 6.7 with local attack vector, low complexity, high privileges required, no user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to Android 11 and 12 devices using the listed MediaTek chipsets. Practical risk depends on device inventory, OEM firmware status, and whether the December 2022 MediaTek fix or downstream vendor update is present.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires local access and high privileges, with no user interaction. Public details are sparse, and no exploit technique is provided in the cited sources.

Researcher notes

Key missing evidence is implementation detail, OEM patch mapping, and exploit telemetry. The strongest public facts are the MediaTek bulletin, CVSS vector, affected chipset and Android version list, CWE-787 classification, and patch ID ALPS07326239.

Mitigation direction

  • Identify Android devices using the affected MediaTek chipsets and Android 11 or 12.
  • Check OEM and MediaTek guidance for patch ALPS07326239 availability.
  • Prioritize firmware or security updates that include the December 2022 MediaTek bulletin fix.
  • Retire or isolate affected devices that cannot receive vendor updates.

Validation and detection

  • Confirm device chipset models against the affected MediaTek product list.
  • Verify Android version is 11.0 or 12.0 on potentially affected devices.
  • Check vendor firmware notes for ALPS07326239 or the December 2022 MediaTek bulletin.
  • Review endpoint telemetry for unexpected privileged local display-component crashes, where available.
