RHSA-2026:57200 PUBLISHED CVSS 7.5 HIGH

A flaw was found in rustls-webpki. A remote attacker, by influencing an application to parse a specially crafted Certificate Revocation List (CRL) that contains an empty `onlySomeReasons` value in its `issuingDistributionPoint` extension, could trigger a panic. This vulnerability leads to a denial of service (DoS) in applications that explicitly enable CRL revocation checking.
