Description
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`.
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.
