Linux Distros Unpatched Vulnerability : CVE-2026-6731

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - X.509 name constraint bypass via the Subject Common Name when treated as a DNS-type name. A certificate whose Subject CN violates an issuing CA's DNS name...

gnutls: GnuTLS: Policy bypass due to case-sensitive nameConstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

Security Bulletin: IBM Cloud Pak for Data System (CPDS 1.0) is affected by multiple vulnerabilities in the cryptography package

Summary IBM Cloud Pak for Data System CPDS 1.0 uses the Python cryptography package, which is affected by multiple security vulnerabilities. CVE-2026-34073 involves improper certificate validation where DNS name constraints are only validated against SANs within child certificates and not the "pe...

CVE-2026-42304

Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.4.0rc2, the twisted.names module is vulnerable to a Denial of Service DoS attack via resource exhaustion during DNS name decompression. A remote, unauthenticated attacker can exploit this by sending...

USN-8380-1 twisted vulnerability

It was discovered that Twisted incorrectly handled DNS name decompression. A remote attacker could possibly use this issue to cause Twisted to consume excessive resources, leading to a denial of service...
