Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 458331

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: serialize accept_q access
 bt_sock_poll() walks the accept queue without synchronization, while child teardown can unlink the same
 socket and drop its last reference. The unsynchronized accept queue walk has existed since the initial
 Bluetooth import. Protect accept_q with a dedicated lock for queue updates and polling. Also rework
 bt_accept_dequeue() to take temporary child references under the queue lock before dropping it and locking
 the child socket. (CVE-2026-52918)

Solution

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