CVE-2026-5291 is a medium-severity vulnerability in the WebGL component of Google Chrome caused by an inappropriate implementation. In Google Chrome versions prior to 146.0.7680.178, a remote attacker could use a crafted HTML page to cause disclosure of potentially sensitive information from process memory. Available reporting identifies the issue as affecting WebGL and resulting in unintended exposure of memory contents to web content, indicating an information disclosure condition rather than direct code execution.
