CVE-2022-25750

Memory corruption via BTHOST double free

Published Oct 17, 2022 · Updated May 13, 2025

Memory corruption in BTHOST in Qualcomm Snapdragon Mobile allows local users to corrupt memory during Bluetooth audio activity. BTHOST releases the same memory twice while music playback and calls occur over a Bluetooth headset, leaving allocator state corrupted. The trigger requires concurrent music playback and call handling through a Bluetooth headset, and Qualcomm has not disclosed whether exploitation causes a crash or code execution.
