Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-12 Android-12LAndroid ID: A-212467440

Recommended fix High confidence

Android 13 (which includes all May 2022 and later security patches)

  1. Apply the May 2022 Android Security Bulletin patch to the device. This patch is delivered through the monthly security update and includes the fix for the intent redirection vulnerability in OngoingCallController.kt.
  2. Verify the device has received the May 2022 security patch level (or later) by checking Settings > About Phone > Security Patch Level.
  3. Ensure the patch is applied through your EMM/MDM solution or carrier/OEM firmware update channel.
  4. After patching, verify that non-exported activities can no longer be launched via intent redirection from the OngoingCallController component.
Caveat Upgrading to Android 13 may introduce UI changes, app compatibility considerations, and may require re-verification of enterprise mobility management policies
