CVE-2025-68305 is a race-induced use-after-free vulnerability in the Linux kernel Bluetooth HCI socket subsystem. Concurrent socket binding and socket write iteration can cause hci_sock_bind processing to free a pending management command before the write path finishes using it. syzbot detected a slab-use-after-free read in mgmt_pending_remove during set_link_security processing. The fix synchronizes the competing operations using hci_dev_lock.
