  • Engineer — Plan: CVE-2026-98432 affects Linux MPTCP implementation with a public PoC on GitHub, but EPSS is 0.00 and it is not KEV-listed, so active exploitation pressure is low; audit whether MPTCP is enabled on your Linux hosts and schedule kernel patching this cycle.
  • SOC/IR — Plan: The SANS ISC diary covers detection approaches for MPTCP traffic; with a public PoC now available, build or review detections for anomalous MPTCP subflow activity on Linux endpoints and edge devices before exploitation pressure rises.
