CVE-2026-98172

Description

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix smbd_connection leak on cifs_get_tcp_session() error When an RDMA connection is successfully established via smbd_get_connection() but cifs_get_tcp_session() later fails (e.g. kthread_create() returns an error), the error path frees tcp_ses without first destroying the smbd_connection. Fix this by calling smbd_destroy() in the out_err cleanup path before kfree(tcp_ses). smbd_destroy() safely handles the case where smbd_conn is NULL, so it can be called unconditionally.
