Senserva AI Opinion for KB5072936
KB5072936 patches CVE-2026-20803, a High severity flaw (CVSS 7.2) affecting SQL Server 2022 and the newer SQL Server 2025 across GDR and CU 22 servicing branches. Exposure is limited to organizations running these specific SQL Server versions on x64, and the EPSS is only 1 percent with no CISA KEV or ransomware association. The notable point is that a single fix spans three servicing paths, so you must apply the update matching your existing branch rather than assuming one package fits all instances.
Do this: Inventory your SQL Server 2022 and 2025 instances, confirm whether each is on the GDR or CU 22 branch, and apply the matching KB5072936 package.
