Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim actively navigate to an attacker-controlled HTML page in a vulnerable Chrome version (prior to 152.0.7977.65), satisfying the UI:R condition in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) is high on paper: network-delivered, low complexity, no privileges required, and full impact within the sandbox. … 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 WebRTC session negotiation or media-stream handling logic designed to trigger a use-after-free condition in Chrome's WebRTC implementation. When a victim browses to the page - for example, via a phishing link or a compromised advertisement - the UAF is triggered during media processing, allowing the attacker to execute arbitrary code within Chrome's sandboxed renderer process. … |
| Remediation | The primary remediation is to upgrade Google Chrome to version 152.0.7977.65 or later, which is confirmed as the patched release per the Chrome 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. |
