Update summary
Fixes 15 CVEs. Most severe CVSS 9.0 (Critical). EPSS exploit probability up to <1%. Among the lower half of tracked Microsoft updates by EPSS exploit probability.
KB5135241 is the November 2026 servicing update for .NET 10.0, and it is unusual because the same fix set ships for Windows, Linux, and Mac OS, so a mixed fleet needs patching on all three platforms, not just Windows. It addresses 14 CVEs with a highest Severity of Critical (CVSS 9.0), though none are in CISA KEV or tied to ransomware, so there is no confirmed active exploitation yet. The exposure is any server, container image, or developer machine running .NET 10.0, which is easy to miss because many apps carry their own runtime.
Do this: Inventory every host and container image running .NET 10.0, deploy KB5135241 to the shared runtime first, and rebuild or redeploy any self-contained apps that bundle their own copy.
