NewCVE-2026-34764 (opens in a new tab)How to fix?
Upgrade electron to version 39.8.5, 40.8.5, 41.1.0, 42.0.0-alpha.5 or higher.
Overview
electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.
Affected versions of this package are vulnerable to Use After Free in the release callback of the paint event, when offscreen rendering with GPU shared textures is enabled. An attacker can cause a crash or memory corruption by invoking the callback after its backing native state has been freed.
Note: This is only exploitable if offscreen rendering is used with webPreferences.offscreen: { useSharedTexture: true } enabled.
Workaround
This vulnerability can be mitigated by ensuring texture.release() is called promptly after the texture has been consumed, before the texture object becomes unreachable.
