{"schema":"threatline.record/2","record":{"id":"CVE-2026-114124","aliases":["GHSA-h3v5-h239-pg29"],"summary":"Electron: Off-screen rendering on macOS trusts GPU-supplied frame geometry","details":"### Impact\nIn offscreen rendering mode on macOS, frame data received from the GPU process was not fully validated by the main process. A compromised GPU process could cause the main process to read out-of-bounds memory while producing `paint` event images, disclosing memory or crashing the app. GHSA-pfmc-3mgc-p6fp covers the same issue on the other capture paths.\n\nApps are only affected if they use offscreen rendering (`webPreferences.offscreen`) on macOS and an attacker has separately gained code execution in the GPU process. Apps that do not use offscreen rendering are not affected.\n\n### Workarounds\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n* `45.0.0-alpha.9`\n* `44.4.3`\n* `43.7.3`\n* `42.11.6`\n\n### For more information\nIf you have any questions or comments about this advisory, email us at
