Security readout for executives and security teams
Plain-English summary
A malicious webpage can exploit a memory safety flaw in vulnerable Google Chrome versions after persuading a user to visit it. Successful exploitation could run attacker-controlled code outside Chrome’s sandbox, potentially exposing data, altering systems, or disrupting operations.
Executive priority
Treat as an urgent browser update because successful exploitation could escape the sandbox and compromise endpoint confidentiality, integrity, and availability. Accelerate remediation broadly, while recognizing that the supplied sources do not establish active exploitation.
Technical view
CVE-2026-79047 is a CWE-416 use-after-free vulnerability in Chrome’s Views component. The supplied record describes remote code execution outside the sandbox through crafted HTML, requiring user interaction but no privileges. Chrome versions before 152.0.7977.65 are described as vulnerable.
Likely exposure
Endpoints running Google Chrome earlier than 152.0.7977.65 are potentially exposed when users can open attacker-controlled or compromised webpages. The supplied evidence does not identify affected operating systems, deployment configurations, or other Chromium-based products.
Exploitation context
Exploitation requires social engineering that causes a user to open crafted HTML. The CVSS score is 9.6 and Chromium severity is High. The supplied bundle marks this CVE as absent from KEV and provides no evidence of active exploitation or public exploit availability.
Researcher notes
The core condition is a use-after-free in Views, categorized as CWE-416. The supplied material does not disclose the vulnerable object lifecycle, affected platforms, proof-of-concept availability, or technical patch details. The structured affected entry lists 152.0.7977.65, while the description says versions prior to it; validation should follow the description and vendor release guidance.
Mitigation direction
- Update Google Chrome to version 152.0.7977.65 or later.
- Prioritize browsers on internet-facing, privileged, and sensitive-data endpoints.
- Use enterprise browser management to accelerate deployment and prevent unsupported versions.
- Review Google and Chromium guidance for any additional platform-specific measures.
Validation and detection
- Inventory installed Chrome versions across managed and unmanaged endpoints.
- Confirm no Chrome installation remains below 152.0.7977.65.
- Verify update policies are enforced and devices successfully restarted Chrome.
- Monitor vendor guidance for revised affected-version or exploitation information.
