CVE-2026-114124— Electron: Off-screen rendering on macOS trusts GPU-supplied frame geometry

Quick assessment

Affected
electron electron
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Electron 是一个用于使用 JavaScript、HTML 和 CSS 开发跨平台桌面应用程序的框架。在版本 42.11.6、43.7.3、44.4.3 和 45.0.0-alpha.9 之前，主进程未对 macOS 离屏渲染场景中来自 GPU 进程的帧数据进行完整验证。若攻击者已在 GPU 进程中单独获得代码执行权限，则可提供不一致的帧几何信息，导致主进程在生成绘制事件图像时读取越界内存，从而泄露内存内容或造成应用程序崩溃。该问题已在版本 42.11.6、43.7.3、44.4.3 和 45.0.0-alp

Vulnerability Title
Electron: Off-screen rendering on macOS trusts GPU-supplied frame geometry
Source: CVE Program / CVE List V5
Vulnerability Description
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9, frame data received from the GPU process for macOS offscreen rendering was not fully validated by the main process. An attacker who had separately gained code execution in the GPU process could provide inconsistent frame geometry and cause the main process to read out-of-bounds memory while producing paint event images, disclosing memory or crashing the application. This issue is fixed in versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9.
