Overview
What is CVE-2024-35869?
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.
