Summary
CVE-2025-40103 affecting package kernel for versions less than 6.6.117.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

smb: client: Fix refcount leak for cifssbtlink

Fix three refcount inconsistency issues related to cifs_sb_tlink.

Comments for cifs_sb_tlink state that cifs_put_tlink() needs to be called after successful calls to cifs_sb_tlink(). Three calls fail to update refcount accordingly, leading to possible resource leaks.
