Out of bounds write in ANGLE in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox-escaping remote code execution in Google Chrome (desktop, versions prior to 152.0.7977.65) stems from an out-of-bounds write in ANGLE, Chrome's OpenGL ES/Direct3D graphics translation layer. A remote attacker who lures a user to a crafted HTML page can execute arbitrary code outside the renderer sandbox, giving native code execution on the host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open or be redirected to an attacker-controlled HTML page in a vulnerable Chrome build (before 152.0.7977.65) - UI:R means user interaction (visiting/rendering the page) is mandatory, and no authentication is needed (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed but lean toward high priority for a browser. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or compromises a web page containing crafted graphics content that triggers the ANGLE out-of-bounds write, then drives a target to it via phishing, a malicious ad, or a watering-hole site. When the victim's pre-152.0.7977.65 Chrome renders the page, the memory corruption is triggered in ANGLE and, upon successful exploitation, runs attacker code outside the browser sandbox on the host. … |
| Remediation | Vendor-released patch: 152.0.7977.65 - update Chrome to 152.0.7977.65 or later on all desktop platforms and restart the browser to apply it (verify via chrome://settings/help); managed fleets should push the update through their enterprise management/auto-update channel per https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
