DEBIAN-CVE-2026-56822

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the OcspServerCertificateValidator forwards the SslHandshakeCompletionEvent before the asynchronous OCSP validation completes. This allows the client's downstream handlers to se...

CVE-2026-56821

CVE-2026-56821 (Netty) affects Netty’s OcspServerCertificateValidator. Prior to 4.1.136.Final and 4.2.16.Final, it flags an out-of-date OCSP response but does not stop processing, causing an expired GOOD response to be treated as VALID. This can allow an on-path attacker to replay a stale GOOD OC...

CVE-2026-56821

A flaw was found in netty-handler-ssl-ocsp, a component of the Netty network application framework. The Online Certificate Status Protocol OCSP stapling validator in this component does not properly check certificate revocation status. This can allow an attacker to use revoked certificates withou...
