In the Linux kernel, the following vulnerability has been resolved:
smb: client: Fix refcount leak for cifs_sb_tlink
Fix three refcount inconsistency issues related to cifs_sb_tlink.

called after successful calls to cifs_sb_tlink(). Three calls fail to
update refcount accordingly, leading to possible resource leaks.
