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...

CVE-2026-9636

CVE-2026-9636 affects Rockwell CompactLogix 5380, ControlLogix 5580, and EN4 communications modules. The issue is in CIP Security certificate revocation handling: the controller may fail to reject certificates signed by intermediates that have been revoked via a CRL, potentially allowing a networ...

Linux Distros Unpatched Vulnerability : CVE-2026-59818

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - etcd is a distributed key-value store for the data of a distributed system. Prior to 3.5.32 and 3.6.13, when etcd is configured with --listen-client-http-urls t...

CVE-2026-59818

A flaw was found in etcd, a distributed key-value store. When etcd is configured to use separate listeners for HTTP and gRPC client endpoints, the Certificate Revocation List CRL is not properly enforced on the gRPC listener. This oversight allows a client with a revoked certificate to successful...

CVE-2026-59818 etcd: gRPC client listener does not enforce `--client-crl-file` certificate revocation

etcd is a distributed key-value store for the data of a distributed system. Prior to 3.5.32 and 3.6.13, when etcd is configured with --listen-client-http-urls to split HTTP and gRPC client endpoints onto separate listeners, the --client-crl-file Certificate Revocation List is not enforced on the...

Medium: aws-nitro-tpm-tools

Issue Overview: A logic error in CRL distribution point validation in AWS-LC before 1.71.0 causes partitioned CRLs to be incorrectly rejected as out of scope, which allows a revoked certificate to bypass certificate revocation checks. To remediate this issue, users should upgrade to AWS-LC 1.71.0...
