OOB read is primarily an info leak requiring victim navigation (UI:R) and reliable chaining (AC:H); code execution and scope change are only potential, so I keep S:U with high confidentiality, low integrity, no availability impact.

Out of bounds read in WebGL in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Out-of-bounds read in the WebGL component of Google Chrome before 153.0.8010.36 lets a remote attacker who lures a victim to a crafted HTML page potentially execute arbitrary code outside the browser sandbox. Chromium rates the security severity as High, and a vendor patch is available; no public exploit has been identified and CISA SSVC records exploitation as none, with EPSS at a low 0.28% (20th 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 that runs crafted WebGL content in Chrome (UI:R), so it is not fully drive-by without user navigation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H = 9.6) reflects a worst-case sandbox-escape outcome with scope change, whereas Chromium's own rating of 'High' (not Critical) and the CWE-125 out-of-bounds-read root cause suggest the realistic primitive is an information leak that only 'potentially' leads to code execution when chained. … 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 (see https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html), then fully restart the browser so the new binary loads. … Detailed patch versions, workarounds, and compensating controls in full report. |
