CVE-2026-31673: Linux for Ubuntu 22.04 can be exploited, update now
CVE-2026-31673 · published 5 days ago
Summary
The Linux kernel used in Ubuntu 22.04 (and related Amazon and Azure builds) has a security weakness that could let an attacker gain control of the system. Updating to the latest kernel package from the Ubuntu repositories closes this gap. Apply the newest kernel updates as soon as possible to keep your servers safe.
