Google has shipped a fixed stable-channel build; there is no public exploit identified at time of analysis and CISA has not listed it in KEV. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively load attacker-controlled content - a crafted HTML page - in Google Chrome for macOS on a version below 152.0.7977.65 (UI:R in the CVSS vector confirms required user interaction). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals here are mixed and should be weighed carefully rather than reacting to the headline 9.6. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page that grooms the browser heap and triggers the Views use-after-free, then serves the link via phishing, malvertising, or a compromised site. When a macOS Chrome user on a vulnerable version visits the page, the dangling pointer is exploited to escape the sandbox and execute code with browser-process privileges. … |
| Remediation | Vendor-released patch: update Google Chrome to 152.0.7977.65 or later on macOS via Chrome's built-in updater (chrome://settings/help) and relaunch the browser to complete installation, since the fix does not take effect until restart. … Detailed patch versions, workarounds, and compensating controls in full report. |
