Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 465782

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: SCO: Fix use-after-free in
 sco_recv_frame() due to missing sock_hold sco_recv_frame() reads conn->sk under sco_conn_lock() but
 immediately releases the lock without holding a reference to the socket. A concurrent close() can free the
 socket between the lock release and the subsequent sk->sk_state access, resulting in a use-after-free.
 Other functions in the same file (sco_sock_timeout(), sco_conn_del()) correctly use sco_sock_hold() to
 safely hold a reference under the lock. Fix by using sco_sock_hold() to take a reference before releasing
 the lock, and adding sock_put() on all exit paths. (CVE-2026-31408)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
