CVE-2026-114124 is a low-severity flaw (CVSS 3.9) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 memo
