A walkthrough of a recurring type-confusion pattern in Windows RPC servers: when an interface accepts an FC_BINDING_CONTEXT handle without checking its object type, attackers can feed one context-handle type where another is expected. The pattern yielded CVE-2025-48815 (ssdpsrv), CVE-2025-53143 (MQQM) and CVE-2025-54104 (mpssvc). https://core-jmp.org/2026/06/from-context-handle-to-type-confusion-windows-rpc-2/
Post summary
The article discloses a Windows RPC type‑confusion vulnerability pattern that produced three new CVEs, explaining the mechanism but not providing PoC, exploit, or patch information.
