CVE-2024-50029 at MITRE

Description

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

Bluetooth: hci_conn: Fix UAF in hci_enhanced_setup_sync

This checks if the ACL connection remains valid as it could be destroyed
while hci_enhanced_setup_sync is pending on cmd_sync leading to the
following trace:
