CVE-2026-114406: Red Hat ca-certificates Certificate Trust Vulnerability

Sources read

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

The system certificate authority store in Red Hat products includes root CA certificates that signed intermediate CA certificates with weak private keys issued by eMudhra. This flaw allows a man-in-the-middle attacker to issue certificates for arbitrary host names.

Why does it matter?

Attackers can leverage this vulnerability to cause TLS/SSL clients to connect to malicious sites, resulting in confidentiality and integrity compromises.

What should be done?

  • Follow vendor advisories
  • Apply updated ca-certificates packages
  • Maintain an updated system certificate store
Chain of evidence and sources2 verified claims

Red Hat ürünlerindeki sistem sertifika deposu, eMudhra tarafından zayıf özel anahtarlarla imzalanmış ara sertifikalara ait kök CA sertifikalarını içermektedir.

Show the technical text from the sources

The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.
