Ubuntu still has not released patch for Linux 0day RCE in almost 3 weeks

Ubuntu has failed to release kernel patches for nearly three weeks for CVE-2026-98432, a critical remote code execution vulnerability rated CVSS 9.8, leaving its 22.04, 24.04, and 26.04 LTS releases unpatched and exposed. Internet-facing and multi-tenant systems are particularly at risk until patches become available, with Ubuntu providing no estimated timeline for fixes. Administrators currently have no official remedy and must choose between accepting the risk, applying unofficial mitigations, or migrating to already-patched systems.
