Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986798 advisory.

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

 Bluetooth: fix null ptr deref on hci_sync_conn_complete_evt

 This event is just specified for SCO and eSCO link types.
 On the reception of a HCI_Synchronous_Connection_Complete for a BDADDR of an existing LE connection, LE link type and a status that triggers the second case of the packet processing a NULL pointer dereference happens, as conn->link is NULL.
