In PVRSRVBridgeRGXKickTA3D of the PowerVR kernel driver, a missing size check means there is a possible integer overflow that could allow out-of-bounds heap access. This could lead to local escalation of privilege with no additional execution privileges needed.

Security readout for executives and security teams

Plain-English summary

CVE-2021-0880 is a high-severity Android SoC issue in the PowerVR kernel driver. A local attacker could use a missing size check to gain higher privileges on an affected device. The sources do not show remote exploitation or user interaction requirements.

Executive priority

Treat this as a high-priority mobile platform patching issue where affected Android devices are in use. Business urgency is highest for fleets with unmanaged app installation, delayed OEM updates, or unsupported Android hardware.

Technical view

The flaw is an integer overflow in PVRSRVBridgeRGXKickTA3D in the PowerVR kernel driver. The overflow may cause out-of-bounds heap access and local escalation of privilege. It is tracked as CWE-190 with CVSS 3.1 score 7.8.

Likely exposure

Exposure appears limited to Android SoC builds using the affected PowerVR kernel driver. The provided sources do not identify specific device models, OEMs, or chipset versions, so organizations need device and patch-level inventory to scope impact.

Exploitation context

The CVE requires local access with low privileges and no user interaction. It is not listed as CISA KEV in the provided bundle, and the sources do not cite active exploitation or public weaponization.

Researcher notes

The public detail is narrow: Android ID A-270396792, PowerVR kernel driver, missing size check, integer overflow, and possible out-of-bounds heap access. Do not assume affected models or exploit availability beyond the cited records.

Mitigation direction

  • Apply Android security updates covering the April 2023 Android Security Bulletin.
  • Check OEM firmware guidance for affected Android SoC devices.
  • Prioritize managed devices that allow untrusted local apps.
  • Restrict sideloading and untrusted app installation where possible.
  • Track vendor advisories for device-specific remediation status.

Validation and detection

  • Inventory Android devices and identify SoC and GPU driver families.
  • Verify devices have security patches addressing the April 2023 bulletin.
  • Confirm whether managed devices use PowerVR-based Android SoC builds.
  • Review vulnerability management records for CVE-2021-0880 coverage.
  • Document unsupported devices that cannot receive OEM firmware updates.
