Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 459933

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: ksmbd: do not expire session on
 binding failure When a multichannel session binding request fails (e.g. wrong password), the error path
 unconditionally sets sess->state = SMB2_SESSION_EXPIRED. However, during binding, sess points to the
 target session looked up via ksmbd_session_lookup_slowpath() -- which belongs to another connection's
 user. This allows a remote attacker to invalidate any active session by simply sending a binding request
 with a wrong password (DoS). Fix this by skipping session expiration when the failed request was a binding
 attempt, since the session does not belong to the current connection. The reference taken by
 ksmbd_session_lookup_slowpath() is still correctly released via ksmbd_user_session_put(). (CVE-2026-31476)

Solution

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