Uninitialized Use in GamepadAPI in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Uninitialized memory exposure in Google Chrome's GamepadAPI allows an attacker who has already achieved renderer process compromise to read potentially sensitive contents from process memory by serving a crafted HTML page that triggers the flaw. Affected versions are all Chrome releases prior to 150.0.7871.47. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two specific conditions to be met simultaneously. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N initially suggests a moderately serious network-accessible flaw requiring only user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already exploited a separate renderer-level vulnerability in Chrome to gain code execution within the sandboxed renderer process then serves a crafted HTML page that invokes the GamepadAPI in a manner that reads an uninitialized buffer. The uninitialized memory contents - potentially including sensitive data from the process - are returned to the attacker's controlled context, enabling exfiltration. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released fix for this issue. … Detailed patch versions, workarounds, and compensating controls in full report. |
