libcrux has an Incorrect Check of Signer Response Norm During Verification

The ML-DSA verification algorithm as specified in FIPS 204, subsection 6.3 requires verifiers to check that the infinity norm of the deserialized signer response $z$ does not exceed $\gamma1 - \beta$ line 13 of Algorithm 8. The same check is required to be performed during signature generation...

CVE-2026-4428

A flaw was found in AWS-LC, a cryptographic library. A logic error in how the library validates Certificate Revocation List CRL distribution points can cause legitimate partitioned CRLs to be incorrectly rejected. This allows a revoked certificate to bypass certificate revocation checks,...

CVE-2026-4428 CRL Distribution Point Scope Check Logic Error in AWS-LC

A logic error in CRL distribution point validation in AWS-LC before 1.71.0 causes partitioned CRLs to be incorrectly rejected as out of scope, which allows a revoked certificate to bypass certificate revocation checks. To remediate this issue, users should upgrade to AWS-LC 1.71.0 or...
