CVEs this fix closes

Priority	CVE	Title	CVSS	EPSS	Exploitation
High	CVE-2026-60000	sshd in OpenSSH before 10.4 allows remote attackers to cause a denial of service (resource consumption from excessive authentication attempts) because MaxAuthTries was mishandled for GSSAPIAuthentication.	7.5	0.0062	None reported
High	CVE-2026-73283	In sshd in OpenSSH before 10.5, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not.	7.5	0.0015	None reported
Routine	CVE-2026-60001	sshd in OpenSSH before 10.4 does not always honor the minimum authentication delay.	6.5	0.0029	None reported
Routine	CVE-2026-59998	sshd in OpenSSH before 10.4 has an undocumented security-relevant behavior: GSSAPIStrictAcceptorCheck has no value if the server is in Windows Active Directory.	6.5	0.0018	None reported
Routine	CVE-2026-59997	internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.	6.5	0.0018	None reported
