CVE-2026-98172
Description
AI Translation Available
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.
