Process crash via malformed-buffer assertions

Published Oct 14, 2026 · Updated Oct 14, 2026

Assertion DoS in F Prime before 4.2.0 allows remote attackers to crash GenericHub via malformed inter-processor hub traffic. The fromBufferDriver_handler receive path asserts on untrusted deserialization results and message types, and subtracts command-context size without checking for underflow. Exploitation requires access to an unauthenticated hub channel in a deployment that includes GenericHub; the default Ref application excludes this component.
