Transient service interruption via BT controller use-after-free
Published Oct 9, 2025 · Updated Oct 9, 2025
Use-after-free in the Qualcomm Snapdragon BT Controller allows remote authenticated users to cause a transient service interruption. During multi-profile concurrency with QHS enabled, the controller accesses freed memory; Qualcomm has not disclosed the specific object or code path. The condition requires QHS and concurrent Bluetooth profiles, and the documented consequence is transient denial of service rather than persistent device failure.
