GHSA-qpch-gjf6-c9gf
This vulnerability involves a bypass of critical extension enforcement in the parsing of Certificate Revocation Lists (CRLs). Specifically, the ParseCRL_Extensions function does not properly enforce critical extensions, allowing a crafted CRL with an unhandled critical extension to be accepted if it has a trusted signature. This issue only affects builds with CRL support enabled. The severity is assessed as low.
AI Analysis
Technical Summary
CVE-2026-6450 describes a vulnerability in the handling of CRL critical extensions where the ParseCRL_Extensions function fails to enforce critical extensions correctly. As a result, a crafted CRL containing an unhandled critical extension can be accepted as valid if it has a trusted signature. This vulnerability affects only builds with CRL support enabled. No known exploits are reported in the wild, and no patch or remediation information is currently available.
Potential Impact
The impact is limited to the acceptance of a crafted CRL with an unhandled critical extension, potentially allowing bypass of CRL critical extension enforcement. This could affect the validation of certificate revocation status in affected builds. No further impact details or exploitation scenarios are provided.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is available at this time.
