Linux Kernel TCP Flaw With 9.8 CVSS Score Affects Ubuntu, Red Hat and Other Distributions
CVE-2026-98432, a critical flaw in the Linux kernel's TCP implementation, affects Ubuntu, Red Hat Enterprise Linux (RHEL), and other distributions with a CVSS score of 9.8. Anthropic disclosed on October 27 that an artificial intelligence (AI) model generated working exploit code allowing remote attackers without credentials to execute commands as root on vulnerable Linux servers.
Why it matters: Linux administrators and security teams managing Ubuntu, RHEL, or other affected distributions must prioritize patching this critical vulnerability, as unauthenticated remote code execution (RCE) as root represents immediate and severe risk to server infrastructure.
