CVE-2023-45775

Local privilege escalation via unchecked broadcast write

Published Dec 4, 2023 · Updated Aug 2, 2024

Out-of-bounds write in Android 14 Bluetooth System code allows local users to elevate privileges without user interaction. CreateAudioBroadcast in system/bta/le_audio/broadcaster/broadcaster.cc omits bounds checks before writing broadcast data outside its destination buffer. A local low-privileged context can trigger memory corruption and gain higher privileges; no user interaction or extra execution privilege is required.
