GoKawiil Brief

A critical remote code execution vulnerability rated 9.8 on the CVSS scale, tracked as CVE-2026-98432, remains unpatched in Ubuntu's 22.04, 24.04, and 26.04 LTS kernels almost three weeks after disclosure. Canonical has not released updated kernel packages or given a timeline for when fixes will ship.

Why It Matters

GoKawiil's interpretation of the reporting above, not reported fact.

The delay leaves self-hosted and internet-facing Ubuntu servers, especially multi-tenant systems relying on kernel-level isolation, without an official defense against a severe flaw. Administrators are effectively forced to weigh risky options such as running unpatched systems, seeking unofficial mitigations, or migrating workloads to already-patched distributions until Canonical responds.
