Integer overflow in WebGL in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Remote code execution outside the browser sandbox is potentially achievable in Google Chrome versions prior to 152.0.7977.65 through an integer overflow in the WebGL graphics subsystem triggered by visiting a crafted HTML page. The vulnerability affects all Chrome desktop platforms with a high-impact CVSS score of 8.8, though Chromium's internal severity rating of Medium and a low EPSS score of 0.25% (16th percentile) together suggest real-world exploitation remains uncommon at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The user must actively visit an attacker-controlled or attacker-compromised webpage containing malicious WebGL content (UI:R per CVSS vector) - exploitation cannot occur without this interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 base score reflects a network-reachable, low-complexity attack requiring only user interaction (UI:R), with high confidentiality, integrity, and availability impact - a strong signal on paper. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page containing WebGL shader or buffer operations designed to trigger the integer overflow with a precisely controlled input size. When a targeted user is socially engineered or redirected to visit the page - via phishing email, malicious ad, or compromised website - Chrome's WebGL subsystem processes the crafted data, the integer wraps, and the resulting memory corruption provides a primitive that could be leveraged for arbitrary code execution within or potentially outside the renderer sandbox. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later, as documented in the stable channel release 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. |
Recommended ActionAI
Within 24 hours, verify Chrome auto-update status is enabled enterprise-wide or immediately deploy stable channel update 152.0.7977.65 to all affected systems; establish monitoring for deployment completion. …
