Vulnerability from github – Published: 2025-02-27 18:31 – Updated: 2025-02-27 18:31

Details

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

Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set

hci_cmd_sync_queue shall return an error if HCI_UNREGISTER flag has been set as that means hci_unregister_dev has been called so it will likely cause a uaf after the timeout as the hdev will be freed.

Severity ?

7.8 (High)
