Linux Kernel TCP Flaw CVE-2026-98432 (CVSS 9.8) Gets Public PoC Exploit
- Engineer — Act: Remote unauthenticated root RCE in the Linux kernel TCP stack with a public GitHub PoC is a patch-now event regardless of the low EPSS snapshot — check Ubuntu/RHEL kernel errata and patch all internet-exposed Linux hosts this sprint.
- SOC/IR — Plan: No confirmed wild exploitation yet, but the public PoC for unauthenticated root RCE means weaponization is imminent — build detections for anomalous TCP session patterns and unexpected root-child process spawning on Linux servers before active campaigns emerge.
- Leader — Plan: A CVSS 9.8 kernel-level RCE spanning Ubuntu and RHEL has board-question potential if exploitation begins; confirm with engineering that Linux patch cycles are accelerated and prepare a brief so leadership isn’t caught off-guard when it escalates.
- Signals: CVE-2026-98432 — CISA KEV: not listed, EPSS 0.00, public PoC on GitHub
