| CVE-2026-55653 | 2 Openssh, Redhat | 6 Openssh, Enterprise Linux, Hardened Images and 3 more | 2026-06-24 | 4.3 Medium |
| A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS). | ||||

| A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session. | ||||
| CVE-2026-55654 | 2 Openssh, Redhat | 6 Openssh, Enterprise Linux, Hardened Images and 3 more | 2026-06-24 | 3.7 Low |
| A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service. | ||||
| CVE-2023-35812 | 1 Openssh | 1 Openssh | 2026-04-15 | 5.3 Medium |
| An issue was discovered in the Amazon Linux packages of OpenSSH 7.4 for Amazon Linux 1 and 2, because of an incomplete fix for CVE-2019-6111 within these specific packages. The fix had only covered cases where an absolute path is passed to scp. When a relative path is used, there is no verification that the name of a file received by the client matches the file requested. Fixed packages are available with numbers 7.4p1-22.78.amzn1 and 7.4p1-22.amzn2.0.2. | ||||
| CVE-2024-39894 | 1 Openssh | 1 Openssh | 2026-04-15 | 7.5 High |
| OpenSSH 9.5 through 9.7 before 9.8 sometimes allows timing attacks against echo-off password entry (e.g., for su and Sudo) because of an ObscureKeystrokeTiming logic error. Similarly, other timing attacks against keystroke entry could occur. | ||||
