Details

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

Bluetooth: hci_conn: Fix memory leaks

When hci_cmd_sync_queue() failed in hci_le_terminate_big() or hci_le_big_terminate(), the memory pointed by variable d is not freed, which will cause memory leak. Add release process to error path.

Severity ?

5.5 (Medium)
