sshd(8) in Portable OpenSSH versions 8.5p1 to 9.7p1 (inclusive). Race condition resulting in potential remote code execution. A race condition in sshd(8) could allow remote code execution as root on non-OpenBSD systems. This attack could be prevented by disabling the login grace timeout (LoginGraceTime=0 in sshd_config) though this makes denial-of service against sshd(8) considerably easier. For more information, please refer to the release notes [1] and the report from the Qualys Security Advisory Team [2] who discovered the bug.
