Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 464435

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: unset conn->binding on failed
 binding request When a multichannel SMB2_SESSION_SETUP request with SMB2_SESSION_REQ_FLAG_BINDING fails
 ksmbd sets conn->binding = true but never clears it on the error path. This leaves the connection in a
 binding state where all subsequent ksmbd_session_lookup_all() calls fall back to the global sessions
 table. This fix it by clearing conn->binding = false in the error path. (CVE-2026-31409)

Solution

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