What Changed
Google released 37 Stable-channel security fixes and 28 Extended Stable fixes, including multiple Critical memory-safety vulnerabilities; some issue details remain restricted during rollout.
What To Validate Now
- Inventory. Locate Google Chrome Stable on Windows, macOS, and Linux and Extended Stable on Windows and macOS deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: Chrome builds before Stable 155.0.8059.79/.80 or Extended Stable 152.0.7977.167 on the corresponding desktop platforms. Do not infer applicability from product family or severity alone.
- Remediate. Apply Chrome Stable 155.0.8059.79/.80 on Windows and macOS, 155.0.8059.79 on Linux, or Extended Stable 152.0.7977.167 on Windows and macOS through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, 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
Stable and Extended Stable have different target builds and overlapping vulnerability sets. Do not treat beta or early-stable announcements as substitutes, and recheck restricted issue details after Google opens them. Preserve the authority snapshot, asset and owner records, before-and-after versions, change approval, installation output, validation results, exceptions, 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.
