This critical flaw occurs when processing RPC requests and can be exploited without authentication, making it highly dangerous for networked environments.","exploitability":"Exploitation is relatively straightforward with no authentication required, though it may need a specific RPC request pattern to trigger the buffer overflow.","blast_radius":"The vulnerability could affect any system running the RPC Runtime component, potentially allowing attackers to gain full system compromise across multiple networked devices.","remediation":"No fixed version is published in the description, so disable the affected RPC functionality or restrict access to the RPC endpoint until a patch is available.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","rpc","network"],"model":"garnet-coder","analyzedAt":"2026-10-14T08:49:52.949Z"}}
