Echo: linux: security update to 6.1.180-1

high Tenable Self-Hosted Container Security Plugin ID 465094

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: require source read access for
 duplicate extents FSCTL_DUPLICATE_EXTENTS_TO_FILE passes the source file directly to
 vfs_clone_file_range() or vfs_copy_file_range() without checking the SMB access mask granted to the source
 handle. A handle opened with attribute access can consequently be used to copy file contents into an
 attacker-readable destination. Require FILE_READ_DATA on the source handle before either VFS operation,
 matching other ksmbd data-copy paths. (CVE-2026-64395)

Solution

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