Echo: linux: security update to 6.1.180-1

critical Tenable Self-Hosted Container Security Plugin ID 464807

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: add permission checks for
 FSCTL_DUPLICATE_EXTENTS_TO_FILE The FSCTL_DUPLICATE_EXTENTS_TO_FILE arm of smb2_ioctl() overwrites the
 destination file's data via vfs_clone_file_range() with neither the share-level
 KSMBD_TREE_CONN_FLAG_WRITABLE check nor a per-handle fp->daccess check that the other write-bearing arms
 carry. A client can overwrite destination data on a read-only share, or from a handle opened with only
 FILE_WRITE_ATTRIBUTES (which still yields an FMODE_WRITE filp). FILE_WRITE_ATTRIBUTES-only destination
 handle overwrote the file's data via the clone. Add both checks, matching the FSCTL_SET_SPARSE permission
 fix; require FILE_WRITE_DATA since this writes data. (CVE-2026-64399)

Solution

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