CVE-2026-31478: Linux KVM and GCP kernels could let attackers gain higher privileges
CVE-2026-31478 · published 2 days ago
Summary
Ubuntu 22.04 packages for Linux KVM and several Google Cloud kernel versions have been updated to close a security gap that could let a malicious user increase their access rights on the system. The risk is that an attacker could run commands as an administrator or gain control of the host. Install the latest kernel updates from the Ubuntu repository as soon as possible to protect your environment.
