"TCP Use-After-Free: CVE-2026-98432 / CVSS 9.8" — Hacker News (best) · AI & Technology
CVE-2026-98432 is a bug in the 's handling of incoming connections: memory backing a connection-tracking structure can be freed while still in use, and a remote attacker who times network requests to hit that window (a ) can corrupt kernel memory. Because it is reachable over the network with no credentials or user interaction, it carries a v3.1 base score of 9.8 — the top of the 'Critical' band — and multiple write-ups describe the worst case as
The claim rests on a real CVE record plus vendor advisories (Red Hat's CVE portal, AWS Lightsail docs, CloudLinux's status post), so the identifier, the affected component and the 9.8 score are solidly sourced. The softer part is the 'remote code execution' framing: the CVE and vendor text describe a remotely triggerable use-after-free via specially timed requests, and RCE is the plausible worst case rather than a demonstrated outcome — no in-the-wild exploitation is established in what has surfaced.
Genuinely new: this is a late-October 2026 disclosure, with the CVE record, vendor advisories and press coverage all landing in the same few days around 2026-10-31.
