Vulnerability AssessmentAI
| Exploitation | The victim must visit an attacker-controlled or compromised webpage using Google Chrome prior to version 152.0.7977.65, confirming the UI:R (user interaction required) designation in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reflects that no attacker-side privileges or complex preconditions are needed, but user interaction is required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page designed to trigger the use-after-free condition in Chrome's Chromecast component. A victim browsing to that page with an unpatched Chrome instance causes memory corruption in the renderer process, granting the attacker code execution within Chrome's sandbox. … |
| Remediation | The primary fix is to update Google Chrome to version 152.0.7977.65 or later; the stable channel update is documented at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
