Linux Distros Unpatched Vulnerability : CVE-2026-89134

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A certificate with no dNSName SAN but another SAN type present e.g. registeredID or iPAddress bypassed the Subject CN dNSName name-constraint check. The CN-as-D...

Linux Distros Unpatched Vulnerability : CVE-2026-94417

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - When an application enables both OCSP and CRL revocation checking on one WOLFSSLCTX or certificate manager, wolfSSL skips the CRL check for any peer certificate...

Linux Distros Unpatched Vulnerability : CVE-2026-89133

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wolfSSL versions 5.9.2 and earlier contain a flaw in the X.509 certificate validation logic where it fails to properly enforce NameConstraints extensions when...

Linux Distros Unpatched Vulnerability : CVE-2026-89102

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In wolfSSL versions 5.7.2 through 5.9.2 there is a client-side implementation flaw in RFC 6961, multiple OCSP response stapling, which can lead to certificate...

Linux Distros Unpatched Vulnerability : CVE-2026-93304

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A DTLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client...

DEBIAN-CVE-2026-94417

When an application enables both OCSP and CRL revocation checking on one WOLFSSLCTX or certificate manager, wolfSSL skips the CRL check for any peer certificate that carries no Authority Information Access OCSP URL, and accepts a certificate the loaded CRL lists as revoked. The soft-fail policy f...

CVE-2026-89134

A certificate with no dNSName SAN but another SAN type present e.g. registeredID or iPAddress bypassed the Subject CN dNSName name-constraint check. The CN-as-DNS fallback was gated on cert-subjectCN != NULL && cert-altNames == NULL && !cert-isCA instead of "no dNSName SAN", so an out-of-scope CN...

DEBIAN-CVE-2026-93304

A DTLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client installs read keys derived from a known deterministic key and checks the server's Finished against that same key. An out-of-order...
