Uninitialized resource in WebGL in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data disclosure in Google Chrome's WebGL subsystem (all versions prior to 153.0.8010.36) enables remote attackers to read residual GPU memory belonging to other origins by serving a crafted HTML page to an unpatched user. The root cause is CWE-908 (use of uninitialized resource): Chrome's WebGL implementation exposed GPU-side buffers to JavaScript before zeroing them, allowing fragments of prior rendering operations from cross-origin contexts to be read back. …

Vulnerability AssessmentAI
| Exploitation | The sole prerequisite is that the victim visits an attacker-controlled HTML page using Google Chrome prior to version 153.0.8010.36 (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (Medium) accurately reflects the vulnerability's constrained impact profile: confidentiality leakage is limited (C:L), there is no integrity or availability consequence, and user interaction is required (UI:R). … 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: Chrome 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
