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-2026-60002	ssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re-exchange. (This outcome occurs only on the client side.)	9.4	0.0030	None reported
High	CVE-2026-59996	scp in OpenSSH before 10.4 may place a file in the parent directory of an intended directory when the copy occurs between two remote destinations.	7.7	0.0025	None reported
High	CVE-2026-59995	sftp in OpenSSH before 10.4 does not properly constrain the location of downloaded files when "sftp server:/path ." is used with an attacker-controlled server.	7.5	0.0025	None reported
High	CVE-2026-59999	In sshd in OpenSSH before 10.4, DisableForwarding=yes was supposed to take precedence over PermitTunnel=yes, but did not.	7.5	0.0016	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
