RUSTSEC-2026-0048: CRL Distribution Point Scope Check Logic Error in AWS-LC

CRL Distribution Point Scope Check Logic Error in AWS-LC

A logic error in CRL distribution point matching in AWS-LC allows a revoked
certificate to bypass revocation checks during certificate validation, when
the application enables CRL checking and uses partitioned CRLs with Issuing
Distribution Point (IDP) extensions.

Customers of AWS services do not need to take action. aws-lc-sys contains
code from AWS-LC. Applications using aws-lc-sys should upgrade to the most
recent release of aws-lc-sys.

Workarounds

Applications can workaround this issue if they do not enable CRL checking
(X509_V_FLAG_CRL_CHECK). Applications using complete (non-partitioned)
CRLs without IDP extensions are also not affected.

Otherwise, there is no workaround and applications using aws-lc-sys should
upgrade to the most recent releases of aws-lc-sys.

See advisory page for additional details.

No repository file, test, or entry point is named. Start by reviewing the aws-lc-sys dependency and the RUSTSEC-2026-0048 advisory, then determine whether docs.rs needs a dependency update or another change; done means the requested remediation is defined and verified without leaving the vulnerable version in use.
