What Changed
sg3_utils could be made to run programs as an administrator if it received specially crafted input. 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, Ubuntu 14.04 (trusty) 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-8874-1. Do not infer applicability from a binary package name, a generic kernel label, or the number of CVEs alone.
- Remediate. Install the fixed source-package versions listed by Ubuntu through the supported security or ESM channel.
- Validate. Confirm the installed source-package version, test representative sg3_utils functions and recovery paths, and document exceptions.
- 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
Validate SCSI inventory, device discovery, enclosure, multipath, storage-management, monitoring, and automation workflows after updating. 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.
