CVE-2024-35869 Details
Description
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.
A vulnerability in the Linux kernel's SMB client handling of Distributed File System (DFS) referrals can lead to use-after-free errors. This issue arises because the kernel does not properly manage the reference counts of session objects when traversing DFS referrals and performing DFS failover operations. The vulnerability is present in the stable Linux kernel versions 6.4 and later.
Users can upgrade to the latest stable version of the Linux kernel, where this vulnerability has been addressed.
