Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Remote crafted page needs only a user visit (UI:R, PR:N, AC:L); sandbox escape crosses a trust boundary (S:C) yielding full code execution and thus high C/I/A.

Buffer overflow in WebGL in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Remote code execution in Google Chrome prior to 153.0.8010.36 allows a remote attacker to escape the renderer sandbox and run arbitrary code on the host by luring a victim to a crafted HTML page that triggers a heap buffer overflow in the WebGL implementation. Chromium rates this Critical and the CVSS 9.6 score reflects a scope-changing sandbox escape; no public exploit is identified at time of analysis, and EPSS is low at 0.29% (21st percentile). …

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 153.0.8010.36) - that user interaction (UI:R) is the primary limiting factor; no authentication or pre-existing privileges are needed (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H = 9.6) describes a network-reachable, low-complexity, unauthenticated attack needing only that the victim open a malicious page (UI:R), with full confidentiality/integrity/availability impact across a scope boundary. … 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: update Google Chrome to 153.0.8010.36 or later via the stable channel; on desktop, use chrome://settings/help to force the update and then fully relaunch the browser so the new build is loaded. … Detailed patch versions, workarounds, and compensating controls in full report. |
