At least one of them is actively exploited (CISA KEV), so this is a deploy-first update.

Update summary
Fixes 43 CVEs. At least one is actively exploited (CISA KEV). Most severe CVSS 9.8 (Critical). EPSS exploit probability up to 71%. Among the top 25% of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Windows 11 Version 24H2 for ARM64-based Systems has shipped since this one: KB5043049 (2024-09-10). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5041580 is a further August 2024 package for Windows 11 version 24H2 and Windows 10 1809, resolving forty three CVEs including CVE-2024-21302 alongside the shared CVE-2024-38178 and CVE-2024-38193 issues. It carries the same Critical, CVSS 9.8 top severity, 71 percent EPSS score, and CISA KEV listing as its sibling August packages, confirming active exploitation. The presence of an older CVE-2024-21302 identifier alongside newer bugs suggests this rollup also folds in a previously unaddressed fix.
Do this: Install KB5041580 across Windows 11 24H2 and Windows 10 1809 fleets this August 2024 cycle.
