CVE-2026-34770 · Electron: Use-after-free in PowerMonitor on Windows and macOS
Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.1, 40.8.0, and 41.0.0-beta.8, apps that use the powerMonitor module may be vulnerable to a use-after-free. After the native PowerMonitor object is garbage-collected, the associated OS-level resources (a message window on Windows, a shutdown handler on macOS) retain dangling references. A subsequent session-change event (Windows) or system shutdown (macOS) dereferences freed memory, which may lead to a crash or memory corruption. All apps that access powerMonitor events (suspend, resume, lock-screen, etc.) are potentially affected. The issue is not directly renderer-controllable. This issue has been patched in versions 38.8.6, 39.8.1, 40.8.0, and 41.0.0-beta.8.
