Buffer overflow in WebRTC in Google Chrome prior to 153.0.8010.36 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 the WebRTC component of Google Chrome prior to 153.0.8010.36 allows a remote unauthenticated attacker to execute arbitrary code within the Chrome renderer sandbox by luring a user to a crafted HTML page. The RCE is sandbox-confined (CVSS S:U), meaning a chained sandbox-escape exploit would be needed for full host-level compromise. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a user to actively visit or be redirected to an attacker-controlled HTML page using a vulnerable Chrome version (prior to 153.0.8010.36) - reflected in UI:R. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 base score reflects high confidentiality, integrity, and availability impact within the sandbox, but Chromium's own security team rates the issue 'Medium' - a recurring pattern for sandbox-confined Chrome vulnerabilities where the true blast radius requires a chained exploit. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Google Chrome to version 153.0.8010.36 or later, which contains the vendor-released patch per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
