CVE-2022-50339

Kernel-state corruption via Bluetooth management flag race

Published Sep 16, 2025 · Updated Sep 16, 2025

Race condition in the Linux kernel Bluetooth management code in 6.0 through 6.0.2 allows local users to corrupt kernel state and interrupt service. mgmt_init_hdev sets HCI_MGMT before INIT_DELAYED_WORK initializes the related work item, while mgmt_index_removed can test the flag and cancel that uninitialized work. Triggering requires low-privileged local access and a race between Bluetooth management socket operations; effects are limited to the host kernel.
