CVE-2023-21361

Paired-device privilege escalation via Bluetooth use-after-free

Published Oct 30, 2023 · Updated Aug 2, 2024

Use-after-free in Bluetooth in Google Android 14 allows physically proximate attackers with paired devices to execute code in a privileged process. The Bluetooth component accesses freed memory while processing input from a paired device, enabling code execution in the Bluetooth process. Exploitation requires a paired device, needs no user interaction or additional execution privileges, and compromises the privileged Bluetooth process.
