Red Hat released patched kernels for CVE-2026-98432, a use-after-free vulnerability in Linux TCP code affecting Enterprise Linux 8, 9, and 10. Ubuntu has published fixes for its three newest long-term-support releases to its testing channel, with no timeline for general availability.
Why it matters: Linux administrators running Red Hat Enterprise Linux or Ubuntu need to prioritize patching this remote code execution flaw, which carries a 9.8 CVSS score and requires no authentication to exploit.
