Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 460141

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix locking in
 hci_conn_request_evt() with HCI_PROTO_DEFER When protocol sets HCI_PROTO_DEFER, hci_conn_request_evt()
 calls hci_connect_cfm(conn) without hdev->lock. Generally hci_connect_cfm() assumes it is held, and if
 conn is deleted concurrently -> UAF. Only SCO and ISO set HCI_PROTO_DEFER and only for defer setup listen,
 and HCI_EV_CONN_REQUEST is not generated for ISO. In the non-deferred listening socket code paths,
 hci_connect_cfm(conn) is called with hdev->lock held. Fix by holding the lock. (CVE-2026-53072)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
