CVE-2026-32280 2 Go Standard Library, Golang 2 Crypto/x509, Go 2026-07-02 7.5 High
During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls.
CVE-2026-39828 1 Golang 2 Crypto, Ssh 2026-06-02 6.3 Medium
When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.
CVE-2026-39829 1 Golang 2 Crypto, Ssh 2026-06-02 7.5 High
The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public key authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
CVE-2026-39830 1 Golang 2 Crypto, Ssh 2026-06-02 9.1 Critical
A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited global responses are now discarded.
CVE-2026-39832 1 Golang 2 Crypto, Ssh 2026-05-28 9.1 Critical
When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote host. The client now serializes all constraint extensions. Additionally, the in-memory keyring returned by NewKeyring() now rejects keys with unsupported constraint extensions instead of silently ignoring them.
CVE-2026-39835 1 Golang 2 Crypto, Ssh 2026-05-28 5.3 Medium
SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
CVE-2026-42508 1 Golang 2 Crypto, Ssh 2026-05-28 9.1 Critical
Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both the 'key' and 'key.SignatureKey' are checked for @revoked.
CVE-2026-46595 1 Golang 2 Crypto, Ssh 2026-05-28 10 Critical
Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped.
CVE-2026-27137 2 Go Standard Library, Golang 2 Crypto Tls, Go 2026-04-21 7.5 High
When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly applied, and only the last constraint will be considered.
CVE-2026-33810 2 Go Standard Library, Golang 2 Crypto/x509, Go 2026-04-20 7.5 High
When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.
CVE-2026-32283 2 Go Standard Library, Golang 2 Crypto Tls, Go 2026-04-16 7.5 High
If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3.
