Ubuntu EDK II Updates Fix Four Vulnerabilities
Tech GuruQuick Answer
Ubuntu published USN-8865-1 for EDK II vulnerabilities on Ubuntu 26.04 (resolute) LTS, Ubuntu 24.04 (noble) LTS, Ubuntu 22.04 (jammy) LTS, Ubuntu 20.04 (focal) ESM, Ubuntu 18.04 (bionic) ESM, Ubuntu 16.04 (xenial) ESM. Ubuntu does not state a CVSS base score in this notice. Install the fixed source-package versions from the supported security or ESM channel.
Match USN-8865-1 To Ubuntu Releases And Update
What to do now: Inventory affected Ubuntu releases, compare installed source-package versions with USN-8865-1, install the supported updates, validate dependent workloads, and retain evidence.

What Changed
Several security issues were fixed in EDK II. In general, a standard system update will make all the necessary changes.
What To Validate Now
- Inventory. Locate systems on Ubuntu 26.04 (resolute) LTS, Ubuntu 24.04 (noble) LTS, Ubuntu 22.04 (jammy) LTS, Ubuntu 20.04 (focal) ESM, Ubuntu 18.04 (bionic) ESM, Ubuntu 16.04 (xenial) ESM; record the installed source package, repository pocket, ESM entitlement where applicable, owner, exposure, and dependencies.
- Establish applicability. Match the Ubuntu codename and source package to USN-8865-1. Do not infer applicability from the binary package name, a generic kernel label, or the number of CVEs alone.
- Remediate. Install the fixed Ubuntu source-package versions listed in USN-8865-1 through the supported security or ESM channel.
- Validate. Confirm the installed source-package version, test representative EDK II functions and recovery paths, and document any exception.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Coordinate service or application restart requirements and test dependent workflows. Preserve package-manager output, before-and-after versions, validation results, and rollback evidence.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
