CVE-2026-64016 is a memory-lifetime flaw in the Linux kernel's ksmbd SMB server implementation affecting durable-handle reconnect error handling. After a durable reconnect succeeds, ksmbd_reopen_durable_fd() republishes the same ksmbd_file object into the session volatile-ID table. If smb2_open() subsequently follows a later error path, cleanup performs ksmbd_fd_put(work, fp) and then unconditionally performs ksmbd_put_durable_fd(dh_info.fp). In the affected path, fp and dh_info.fp refer to the same ksmbd_file object. The first put drops the reconnect lookup reference, while the final durable put can invoke a non-session-aware close path that frees the file object without removing the volatile-ID entry that was just republished into the session table. This creates a stale session-table reference to freed memory, resulting in a use-after-free condition and an exploitable kernel memory-safety bug in ksmbd durable reconnect processing.
