Medium (5.9). EPSS 0.7% chance of exploitation in the next 30 days. Fixed in stdlib 1.21.8, 1.22.1.

Verifying a certificate chain which contains a certificate with an unknown public key algorithm will cause Certificate.Verify to panic. This affects all crypto/tls clients, and servers that set Config.ClientAuth to VerifyClientCertIfGiven or RequireAndVerifyClientCert. The default behavior is for TLS servers to not verify client certificates.
