Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The sole triggering condition is that a user running a vulnerable version of Google Chrome (prior to 152.0.7977.65) visits a crafted HTML page, requiring active user interaction (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score reflects a dangerous attack profile: network-reachable, low complexity, no privileges required, and high impact across all three pillars, with only user interaction (UI:R) serving as a barrier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page containing crafted HTML or JavaScript designed to trigger the use-after-free condition in Chrome's Platform component, then lures a target user to visit it via phishing, malvertising, or a watering-hole attack. Upon page load in a vulnerable Chrome version, the freed memory object is accessed, corrupting the heap in a way the attacker controls, resulting in arbitrary code execution within the Chrome renderer sandbox. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which is the vendor-released patch as confirmed by the Chrome Stable Channel update 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. |
