A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections.

The usage of sshpkt_disconnect() on an error, which does | |
| CVE-2025-61985 | Low | 3.6 | < 8.0p1-27.el8_10 | 8.0p1-27.el8_10 | Oct 6, 2025 | ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used. | |
| CVE-2025-61984 | Low | 3.6 | < 8.0p1-27.el8_10 | 8.0p1-27.el8_10 | Oct 6, 2025 | ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file | |

A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying | |
