CVE-2026-34764— Electron 资源管理错误漏洞

Electron has a use-after-free in offscreen shared texture release() callback

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. From 33.0.0-alpha.1 to before 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, apps that use offscreen rendering with GPU shared textures may be vulnerable to a use-after-free. Under certain conditions, the release() callback provided on a paint event texture can outlive its backing native state, and invoking it after that point dereferences freed memory in the main process, which may lead to a crash or memory corruption. Apps are only affected if they use offscreen rendering with webPreferences.offscreen: { useSharedTexture: true }. Apps that do not enable shared-texture offscreen rendering are not affected. To mitigate this issue, ensure texture.release() is called promptly after the texture has been consumed, before the texture object becomes unreachable. This vulnerability is fixed in 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5.

释放后使用

Electron 资源管理错误漏洞

Electron是Electron开源的一个用户编写跨平台桌面应用的 JavaScript 框架。该框架基于 nodejs 和 Chromium 可以使用HTML，CSS实现跨平台桌面应用的编写。 Electron 33.0.0-alpha.1至39.8.5之前版本、40.8.5之前版本、41.1.0之前版本和42.0.0-alpha.5之前版本存在资源管理错误漏洞，该漏洞源于使用GPU共享纹理的离屏渲染时存在释放后重用问题，可能导致崩溃或内存损坏。
