CVE-2026-98432: Linux Kernel IPv4 Use-After-Free with Public PoC

Mon, 02 Nov 2026 20:44:36 +0000

Engineer — Plan: A public PoC exists for this Linux kernel IPv4 UAF, raising exploitation risk despite EPSS 0.00 and no KEV listing; queue kernel patching this sprint and prioritize internet-exposed or multi-tenant Linux hosts where local privilege escalation impact is greatest.
SOC/IR — Learn: No active exploitation, IOCs, or mapped TTPs yet; monitor for KEV listing or PoC weaponization that would warrant a sweep for anomalous kernel-level activity on Linux hosts.
Leader — Skip
Signals: CVE-2026-98432 — CISA KEV: not listed, EPSS 0.00, public PoC on GitHub, reported by 2 collected sources
