NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by AlmaLinux.

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_sync: fix race in hci_cmd_sync_dequeue_once

hci_cmd_sync_dequeue_once() does lookup and then cancel the entry under two separate lock sections. Meanwhile, hci_cmd_sync_work() can also delete the same entry, leading to double list_del() and "UAF".

Fix this by holding cmd_sync_work_lock across both lookup and cancel, so that the entry cannot be removed concurrently.
