CVE-2026-114406: Ca-certificates: distrust emudhra intermediate ca certificates due to security concerns
Noroxi assessment
Priority: Monitor (action score 27/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.31% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
- Fixed version: ca-certificates (AlmaLinux:10) 2026.2.92_v9.0.319-100.3.el10_2; ca-certificates (AlmaLinux:8) 2026.2.92_v9.0.319-81.3.el8_10; ca-certificates (AlmaLinux:9) 2026.2.92_v9.0.319-90.3.el9_8.
Low priority for now. Upgrade to ca-certificates (AlmaLinux:10) 2026.2.92_v9.0.319-100.3.el10_2; ca-certificates (AlmaLinux:8) 2026.2.92_v9.0.319-81.3.el8_10; ca-certificates (AlmaLinux:9) 2026.2.92_v9.0.319-90.3.el9_8 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
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.

Root cause
A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.
