  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: guarantee refcounted children from parent session\n\nAvoid potential use-after-free bugs when walking DFS referrals,\nmounting and performing DFS failover by ensuring that all children\nfrom parent @tcon->ses are also refcounted.  They're all needed across\nthe entire DFS mount.  Get rid of @tcon->dfs_ses_list while we're at\nit, too.",
