What it is

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

smb: client: guarantee refcounted children from parent session

Avoid potential use-after-free bugs when walking DFS referrals,

mounting and performing DFS failover by ensuring that all children

from parent @tcon->ses are also refcounted. They're all needed across

the entire DFS mount. Get rid of @tcon->dfs_ses_list while we're at

it, too.
