Echo: linux: security update to 6.12.29-1

high Tenable Self-Hosted Container Security Plugin ID 462641

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: Fix UAF in
 __close_file_table_ids A use-after-free is possible if one thread destroys the file via __ksmbd_close_fd
 while another thread holds a reference to it. The existing checks on fp->refcount are not sufficient to
 prevent this. The fix takes ft->lock around the section which removes the file from the file table. This
 prevents two threads acquiring the same file pointer via __close_file_table_ids, as well as the other
 functions which retrieve a file from the IDR and which already use this same lock. (CVE-2025-37952)

Solution

Update the linux library and its related packages to version 6.12.29-1 or later.
