The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below.
