CVE-2026-63993: Ubuntu 22.04 Linux kernels could let attackers gain access
CVE-2026-63993 · published 1 day ago
Summary
Several Ubuntu 22.04 kernel packages (canonical/linux-hwe-edge, linux-aws-5.0, linux-aws-5.3, linux-azure, linux-azure-5.3) contain a security weakness that could allow unauthorized users to gain higher privileges on the system. Updating to the latest patched versions removes this risk. Apply the new kernel updates promptly to keep the servers secure.
