Chrome 156.0.8078.79/.80 Fixes 21 Security Flaws
Tech GuruQuick Answer
Google Chrome 156.0.8078.79/.80 fixes 21 security vulnerabilities on desktop, with corresponding fixes in Android 156.0.8078.79. Inventory managed browsers, complete rollout and restarts, validate enterprise policy and critical web applications, monitor exceptions, and retain evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Inventory managed Chrome on Windows, macOS, Linux, and Android, exact running versions, Extended Stable use, browser-management policy, owners, and rollout status. Match operating system and channel to Google's version statement; do not assume a downloaded update is active until the running browser has restarted. Deploy Chrome 156.0.8078.79/.80 on desktop and 156.0.8078.79 on Android through the supported update or enterprise-management channel. Confirm running versions after restart, test authentication, proxies, extensions and critical sites, track devices that missed rollout, and retain management and change evidence.

What Changed
Google fixed 21 security issues, including one Critical memory-corruption issue and nineteen High memory-safety or input-validation issues; Android carries the corresponding desktop fixes unless noted.
What To Validate Now
- Inventory. Inventory managed Chrome on Windows, macOS, Linux, and Android, exact running versions, Extended Stable use, browser-management policy, owners, and rollout status.
- Establish applicability. Match operating system and channel to Google's version statement; do not assume a downloaded update is active until the running browser has restarted.
- Remediate. Deploy Chrome 156.0.8078.79/.80 on desktop and 156.0.8078.79 on Android through the supported update or enterprise-management channel.
- Validate. Confirm running versions after restart, test authentication, proxies, extensions and critical sites, track devices that missed rollout, and retain management and change evidence.
- 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
Google may restrict bug details until adoption is broad. That limits exploit-detail review but does not establish active exploitation; prioritize completion without inventing exposure claims.
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.
