HIGH 8.8

DescriptionCVE.org

Integer overflow in Media in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to potentially exploit heap corruption via a crafted video file. (Chromium security severity: Low)

AnalysisAI

Integer overflow in Google Chrome's Media component allows remote attackers to trigger heap corruption via specially crafted video files. Affects Chrome versions prior to 147.0.7727.55. Attack requires user interaction (opening malicious video file) but no authentication. Successful exploitation enables arbitrary code execution with high impact to confidentiality, integrity, and availability. No public exploit identified at time of analysis. Chromium project rates severity as Low despite CVSS 8.8 score.

Technical ContextAI

Integer overflow (CWE-472) in Chrome's Media subsystem fails to validate video file parameters, allowing heap memory corruption. CVSS vector AV:N/AC:L/PR:N/UI:R indicates network-based delivery requiring user interaction but no privileges. CPE cpe:2.3:a:google:chrome applies to all platforms. Root cause traced to Chromium issue 485115554.

RemediationAI

Vendor-released patch: Google Chrome 147.0.7727.55. Users must immediately upgrade via browser's built-in update mechanism (Settings > About Chrome) or download current stable release from official channels. Update addresses integer overflow through input validation hardening in Media component. Enterprise deployments should prioritize patch distribution through managed update infrastructure. No workaround exists; upgrade is mandatory. Official advisory: https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop.html. Technical details: https://issues.chromium.org/issues/485115554. EPSS score 0.03% indicates low observed exploitation activity.
