[TLS certificate notAfter validated against hardcoded 2025-01-01 string]
AnalysisAI
TLS certificate expiry validation in an Ubuntu-reported component compares the certificate notAfter field against a hardcoded string '2025-01-01' rather than the current system time. Any TLS certificate with a notAfter date after that hardcoded value will pass expiry validation regardless of whether the certificate has actually expired, or conversely, valid certificates may be incorrectly rejected depending on comparison logic. No CVSS vector, CWE classification, or KEV status has been assigned at time of analysis; no public exploit has been identified.
Technical ContextAI
TLS certificate validation requires comparing the certificate's notAfter field against the current wall-clock time to determine whether the certificate is within its validity period. The defect described replaces the dynamic current-time reference with a hardcoded static string '2025-01-01'. Depending on string comparison semantics versus date comparison semantics, this could cause all certificates with notAfter values lexicographically or numerically greater than that string to appear valid indefinitely (bypassing expiry enforcement), or cause certificates valid after 2025-01-01 to be incorrectly evaluated. No CWE identifier has been provided, but this maps conceptually to CWE-295 (Improper Certificate Validation) or CWE-547 (Use of Hard-coded, Security-relevant Constants). The specific library or component within Ubuntu's ecosystem is not named in the available data.
Affected ProductsAI
The affected product is described only as an Ubuntu-ecosystem component that performs TLS certificate notAfter validation. No specific package name, version range, or CPE string has been provided in the available intelligence. The sole reporting source is listed as 'vendor:ubuntu'. Affected version ranges and a canonical vendor advisory URL are not available at time of analysis.
RemediationAI
No patch version has been identified at time of analysis. Upstream fix availability is not confirmed - no GitHub PR, commit, or tagged release has been referenced in the available data. Monitor the Ubuntu Security Notices feed (ubuntu.com/security/notices) for a USN addressing CVE-2026-52060. As a compensating control where the affected component can be identified, consider disabling or isolating services that rely on it for certificate validation and substituting a validated TLS library. Do not treat expired certificates as valid in any interim workaround configuration. No specific advisory URL is available to cite.
