Echo: linux: security update to 6.1.180-1

critical Tenable Self-Hosted Container Security Plugin ID 458652

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: serialize QUERY_DIRECTORY
 requests per file smb2_query_dir() stores a pointer to its stack-allocated private data in the ksmbd_file
 readdir_data. Concurrent QUERY_DIRECTORY requests using the same file handle can overwrite this pointer
 while an iterate_dir() callback is still using it, resulting in a stack use-after-free. Add a per-file
 mutex and hold it while accessing the shared directory enumeration state. The lock covers scan restart,
 dot entry state, readdir_data setup and iteration, and response construction. This prevents another
 request from replacing readdir_data.private before the current request has finished using it and also
 serializes the shared file position. (CVE-2026-64397)

Solution

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