Denial Of Service (DoS)CVE-2026-39835 Published Jun 2, 2026
53
Medium Risk

TL;DR
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.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and if you use the golang.org/x/crypto/ssh functionalities.
Background info
golang.org/x/crypto is vulnerable to Denial Of Service (DoS) in versions 0.0.0 - 0.51.0.
How to fix this
Upgrade the golang.org/x/crypto library to the patch version.
