Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must navigate to a crafted HTML page using an affected version of Google Chrome (prior to 152.0.7977.65) - this is the sole triggering condition (UI:R in CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector reflects a high-severity, network-accessible flaw requiring no attacker authentication and only passive user interaction (visiting a page), with full confidentiality, integrity, and availability impact within the unchanged scope (S:U). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious webpage containing crafted JavaScript that triggers the use-after-free condition in Chrome's V8 engine. When a target user is directed to the page - via phishing link, malvertising, or a compromised legitimate site - Chrome processes the JavaScript and the resulting memory corruption grants the attacker code execution within the Chrome renderer sandbox. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later immediately via Chrome's built-in update mechanism (Settings > Help > About Google Chrome) or by following the stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
