Use after free in WebGL 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's WebGL component affects all desktop builds prior to 152.0.7977.65. A crafted HTML page can trigger a use-after-free (CWE-416) whose exploitation, per the description, yields code execution outside the browser renderer sandbox - a notably severe outcome that Chrome typically confines. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load attacker-controlled content in a vulnerable Chrome build (before 152.0.7977.65) with WebGL enabled, which is the default configuration - the description specifies delivery 'via a crafted HTML page.' The limiting factor is user interaction (CVSS UI:R): the target must navigate to or render the malicious page (direct visit, iframe, ad, or embedded content); no authentication or elevated privileges are needed (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and must be weighed carefully. … 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 | Vendor-released patch: 152.0.7977.65 - update Chrome to 152.0.7977.65 or later via the Chrome Stable channel and relaunch the browser to load the fix (see https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
