Description (CNA)
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8, apps that register an asynchronous session.setPermissionRequestHandler() may be vulnerable to a use-after-free when handling fullscreen, pointer-lock, or keyboard-lock permission requests. If the requesting frame navigates or the window closes while the permission handler is pending, invoking the stored callback dereferences freed memory, which may lead to a crash or memory corruption. Apps that do not set a permission request handler, or whose handler responds synchronously, are not affected. This issue has been patched in versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8.

A flaw was found in Electron, a framework for building desktop applications. This vulnerability, known as a use-after-free, occurs when an application registers an asynchronous permission request handler and a frame navigates or a window closes while the handler is pending. A remote attacker could exploit this by causing the application to attempt to access freed memory. This could lead to a crash of the application or memory corruption, potentially allowing for further unauthorized actions.
