Overview
Affected versions of this package are vulnerable to Use After Free in the tcon_super_cb process. An attacker can cause memory corruption or kernel crashes by triggering a race condition that leads to the use of freed memory during DFS automount expiry and SMB session reconnection. This is only exploitable if a victim has mounted a DFS share with an automounted DFS link from an attacker-reachable server, and the link remains idle long enough to expire.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
