CVE-2026-99091

Daemon crash via incorrect Bluetooth management status

Published Oct 26, 2026 · Updated Oct 26, 2026

Incorrect Bluetooth management replies in Linux allow context-dependent attackers to crash bluetoothd during adapter power-off. In net/bluetooth/mgmt.c, cmd_complete_rsp() passes a command-lookup structure instead of its status field to cmd_status_rsp(), producing an incorrect reply. The observed crash requires pending discovery during shutdown and a client such as bluetoothd 5.72 that mishandles an empty success response; an unauthenticated remote trigger is not established.
