My forecast from last month was only partly right. After the Anthropic Mythos announcements and the deluge of newly discovered vulnerabilities from vendors like Mozilla, Microsoft’s updates were standard fare, 65 CVEs reported in Windows 11 and 58 in Windows 10. The Microsoft Office releases were a bit higher with 19 CVEs or so reported for the online versions.
