kexec-tools is vulnerable to information disclosure. Kdump used the SSH (Secure Shell) “StrictHostKeyChecking=no” option when dumping to SSH targets, causing the target kdump server’s SSH host key not to be checked. This could make it easier for a man-in-the-middle attacker on the local network to impersonate the kdump SSH target server and possibly gain access to sensitive information in the vmcore dumps.
