Echo: linux: security update to 6.1.180-1

critical Tenable Cloud Security Plugin ID 462242

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: run set info with opener
 credentials SMB2 SET_INFO handlers call path-based VFS helpers after checking the access mask granted to
 the SMB handle. Those helpers perform their owner, inode permission and LSM checks using the current ksmbd
 worker credentials. Run the complete SET_INFO dispatch with the credentials captured when the handle was
 opened. This also removes the separate security information credential setup and keeps all SET_INFO
 classes under one credential scope. Direct override_creds() is used because it can nest with the request
 credential overrides already used by rename and link helpers. (CVE-2026-64393)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
