Electron: Use-after-free in WebContents fullscreen, pointer-lock, and keyboard-lock permission callbacks

상세

### Impact 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.

### Workarounds Respond to permission requests synchronously, or deny fullscreen, pointer-lock, and keyboard-lock requests if an asynchronous flow is required.

### Fixed Versions * `41.0.0-beta.8` * `40.7.0` * `39.8.0` * `38.8.6`
