Buffer overflow in WebRTC in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Heap-based buffer overflow in Google Chrome's WebRTC component (versions prior to 152.0.7977.65) enables a remote attacker to execute arbitrary code inside the Chrome renderer sandbox by delivering a crafted HTML page to a victim user. The CVSS score of 8.8 reflects broad impact (C:H/I:H/A:H) with no authentication prerequisite, though code execution is initially sandboxed and scope is unchanged (S:U). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome prior to version 152.0.7977.65 and to navigate to or be redirected to an attacker-controlled HTML page (UI:R per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates low-complexity, network-accessible exploitation requiring only that a user visit a malicious page - a realistic social engineering scenario. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page embedding malicious WebRTC session negotiation logic - such as a manipulated SDP offer or crafted media stream - designed to trigger the heap buffer overflow during WebRTC processing in the Chrome renderer. A victim running unpatched Chrome is directed to the page via phishing, malvertising, or a compromised legitimate site, and upon page load the overflow executes attacker-controlled code within the Chrome renderer sandbox. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later; this is the vendor-confirmed patched release per the 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. |
