CVE-2026-106589 (GCVE-0-2026-106589)

Vulnerability from nvd – Published: 2026-10-06 21:21 – Updated: 2026-10-07 15:46

Summary

In sshd in OpenSSH through 10.6, in certain environments such as QNX 6 and SCO OpenServer 5, sshd-session can unexpectedly have root privileges. This is related to the GatewayPorts and StreamLocalForwarding configuration options, and lack of support for file-descriptor passing and unprivileged allocation of PTY devices.

Severity

2.9 (Low)

CVE-2026-73281 (GCVE-0-2026-73281)

Vulnerability from nvd – Published: 2026-08-11 19:10 – Updated: 2026-08-11 20:16

Summary

In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the session-bind@openssh.com extension.

CVE-2026-106589 (GCVE-0-2026-106589)

Vulnerability from cvelistv5 – Published: 2026-10-06 21:21 – Updated: 2026-10-07 15:46

Summary

In sshd in OpenSSH through 10.6, in certain environments such as QNX 6 and SCO OpenServer 5, sshd-session can unexpectedly have root privileges. This is related to the GatewayPorts and StreamLocalForwarding configuration options, and lack of support for file-descriptor passing and unprivileged allocation of PTY devices.

Severity

2.9 (Low)

CVE-2026-73281 (GCVE-0-2026-73281)

Vulnerability from cvelistv5 – Published: 2026-08-11 19:10 – Updated: 2026-08-11 20:16

Summary

In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the session-bind@openssh.com extension.

Severity

3.5 (Low)
