Ubuntu leaves critical Linux kernel flaw CVE-2026-98432 unpatched for nearly three weeks
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.
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.
- CVE-2026-98432 carries a critical CVSS score of 9.8 and affects Ubuntu 22.04, 24.04, and 26.04 LTS.
- No vendor-supplied kernel patch has been released in almost three weeks since disclosure.
- Self-hosted operators have no official fix and must choose between risk, workarounds, or switching platforms.
