Linux IPv4 TCP Use-After-Free CVE-2026-98432 CVSS 9.8
- Engineer — Plan: Linux kernel TCP UAF with CVSS 9.8 and a public PoC is real exposure for any cloud/Kubernetes workload, but EPSS 0.00 and no KEV listing means no observed exploitation yet; queue patching affected kernel versions within your next maintenance window rather than treating this as an emergency.
- SOC/IR — Learn: No active exploitation, no published IOCs, and no ATT&CK-mapped TTPs to hunt for right now; review the PoC’s exploitation path to understand what kernel panic or anomalous TCP behavior a future detection rule would need to catch.
- Leader — Skip
- Signals: CVE-2026-98432 — CISA KEV: not listed, EPSS 0.00, public PoC on GitHub
