The location of VMware Security Advisories (VMSAs) has changed on May 6, 2024. They are now available from the Broadcom Support Portal. The legacy VMSA URLs still work but are now redirected to the portal, for example: https://www.vmware.com/security/advisories/VMSA-2024-0002.html points to https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/23681.
