• npm electron: < 38.8.6 → fixed in 38.8.6 • npm electron: >= 39.0.0-alpha.1, < 39.8.1 → fixed in 39.8.1 • npm electron: >= 40.0.0-alpha.1, < 40.8.0 → fixed in 40.8.0 • npm electron: >= 41.0.0-alpha.1, < 41.0.0-beta.8 → fixed in 41.0.0-beta.8

Impact 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. Workarounds There are no app side workarounds, you must update to a patched version of Electron. Fixed Versions • `41.0.0-beta.8` • `40.8.0` • `39.8.1` • `38.8.6` For more information If there are any questions or comments about this advisory, please email [email protected]
