What Changed
Google released ten Stable security fixes, including one Critical and six High vulnerabilities, and ten Extended Stable fixes, including two Critical vulnerabilities. The Android release carries the corresponding Desktop security fixes.
What To Validate Now
- Inventory. Locate Google Chrome Stable on Windows, macOS, Linux, and Android 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 155.0.8059.84/.85 on Windows and macOS, 155.0.8059.84 on Linux and Android, or Extended Stable 152.0.7977.169 on Windows and macOS. Do not infer applicability from product family or severity alone.
- Remediate. Apply Chrome Stable 155.0.8059.84/.85 on Windows and macOS, 155.0.8059.84 on Linux and Android, or Extended Stable 152.0.7977.169 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 require different target builds, while Android inherits the corresponding Desktop fixes. Google may keep issue details restricted during rollout; do not use Beta-channel announcements as production remediation. 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.
