CVE-2025-21796: Linux kernel can allow unauthorized code execution
CVE-2025-21796 · published 3 days ago
Summary
The core part of the Linux operating system, including the standard Linux kernel and versions used by Ubuntu and cloud services, contains a flaw that could let attackers run their own code on a server. This could give them control over the affected system. Update to the latest patched kernel versions as soon as possible to close the gap.
