Update summary
Fixes 34 CVEs. At least one is actively exploited (CISA KEV). Most severe CVSS 8.8 (High). EPSS exploit probability up to 4.6%. Among the top half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Windows 11 Version 25H2 for ARM64-based Systems has shipped since this one: KB5087423 (2026-06-09). 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.
KB5072033 is a December 2025 rollup covering Windows 11 25H2 (ARM64 and x64) and Windows 10 1809, fixing 34 CVEs with a highest Severity of High (CVSS 8.8). What stands out is that at least one included CVE is on the CISA KEV list, meaning it has confirmed real-world exploitation, though none are tied to ransomware and peak EPSS remains modest at 5%.
Do this: Prioritize deploying KB5072033 to internet-facing and privileged Windows 11 25H2 and Windows 10 1809 systems first because of the confirmed CISA KEV exploited CVE in this batch.
