About this tag
The rpc vulnerability tag covers security issues in the Windows Remote Procedure Call (RPC) subsystem, a core mechanism that allows processes and services to communicate across process and machine boundaries. Discussions include CVE-2026-20821, an information-disclosure vulnerability that can let a local unauthorized actor access sensitive memory or system information when the vulnerable RPC runtime is invoked. Historical content also covers the Conficker (Downadup) worm, which exploited the MS08-067 patch for a critical remote code execution vulnerability in the Windows Server service, highlighting the importance of patch management. These threads focus on vulnerability details, patching guidance, and lessons for maintaining secure Windows environments.
