## What to check

- Applies to: The 40 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR has published a security advisory covering multiple vulnerabilities discovered in the Linux kernel across multiple Ubuntu releases, including 14.04 ESM, 16.04 ESM, 18.04 ESM, 20.04 ESM, 22.04 LTS, 24.04 LTS, 25.10, and 26.04 LTS. The vulnerabilities enable attackers to achieve arbitrary code execution, privilege escalation, denial of service, and compromise data confidentiality. The advisory references nine Ubuntu security bulletins (USN-8361-2, USN-8388-1 through USN-8393-1, and USN-8421-1, USN-8426-1) issued on 4 June and 11 June 2026. Defenders must prioritize kernel updates across their Ubuntu deployment footprint, starting with the most current and long-term support releases. The breadth of affected versions and the severity of potential impacts require coordinated patching.
