Detection & IOCsextracted from sources · hover to see the quote

  • →Vulnerability is in gatt_end_operation() within gatt_utils.cc — monitor for anomalous GATT operation termination flows in Bluetooth stack processes on Android (AOSP 11, 12, 12L, 13) ↗
  • →No user interaction required and no additional privileges needed — exploit can be triggered remotely over Bluetooth without any victim action; prioritize detection of unexpected Bluetooth GATT traffic patterns ↗
  • →Affected Android versions are 11, 12, 12L, and 13 — scope detection and patch verification efforts to devices running these AOSP versions ↗
  • →Internal Android bug tracker reference A-261068592 can be used to cross-reference patch commits in AOSP Gerrit for diff-based detection of the missing bounds check fix in gatt_utils.cc ↗
  • ·Rated CRITICAL with RCE impact and zero-click, zero-privilege exploitation — no mitigating configuration is documented in the sources; patching via the July 2023 Android Security Bulletin is the only remediation referenced ↗
