How to fix?

Upgrade SLES:16.0.0 google-guest-agent to version 20260529.00-160000.1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream google-guest-agent package and not the google-guest-agent package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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.
