What Changed
Ceph could allow unintended access to network services. 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 22.04 (jammy) LTS, Ubuntu 20.04 (focal) ESM, Ubuntu 18.04 (bionic) 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-8867-1. 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-8867-1 through the supported security or ESM channel.
- Validate. Confirm the installed source-package version, test representative Ceph 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.
