CVE-2023-21113: In multiple locations, there is a possible permission bypass due to a confused deputy.

In multiple locations, there is a possible permission bypass due to a confused deputy. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Security readout for executives and security teams

Plain-English summary

This is an Android local privilege-escalation flaw. A lower-privileged app or local actor could abuse a confused-deputy permission bypass to gain higher privileges without user interaction. The listed affected versions are Android 12, 12L, and 13.

Executive priority

Treat this as a high-priority mobile patching issue, especially for fleets with older Android 12 through 13 devices. There is no provided evidence of active exploitation, but impact is high if a local attacker succeeds.

Technical view

CVE-2023-21113 is a CWE-269 permission-bypass issue in Android, described across multiple locations as a confused-deputy flaw. CVSS 3.1 is 7.8, local attack vector, low complexity, low privileges required, no UI, with high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is most likely on Android 12, 12L, or 13 devices that have not received the Android June 2024 security fixes or equivalent OEM updates.

Exploitation context

The source bundle does not show KEV listing or cited active exploitation. Exploitation requires local access or a low-privileged local context, but does not require user interaction.

Researcher notes

The public description is broad and does not provide exploit detail. References include Android bulletin and AOSP changes in build/soong, frameworks/base, and Wifi module SDK. Avoid assuming a single component root cause beyond the cited confused-deputy permission bypass.

Mitigation direction

  • Apply Android June 2024 security bulletin fixes or later OEM security updates.
  • Prioritize managed Android 12, 12L, and 13 devices below current patch level.
  • Check OEM advisories for device-specific patch availability and timelines.
  • Reduce exposure from untrusted apps on devices awaiting updates.

Validation and detection

  • Inventory Android devices by OS version and security patch level.
  • Confirm affected devices show June 2024 or later Android security patch coverage.
  • Verify OEM firmware includes the referenced Android security bulletin fixes.
  • Track exceptions for devices that cannot receive supported updates.
