Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2026-114124 (opens in a new tab)How to fix?
Upgrade electron to version 45.0.0-alpha.9, 44.4.3, 43.7.3, 42.11.6 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 Out-of-bounds Read via the OnFrameCaptured function in shell/browser/api/frame_subscriber.cc, where a captured video frame's layout metadata (content_rect and coded_size) is not validated against the actual shared memory mapping size before constructing an SkBitmap over it. An attacker with code execution in the GPU process can supply a frame whose content_rect exceeds the bounds of the shared memory region, causing an out-of-bounds read when the bitmap pixels are accessed.
Note: This is only exploitable when the application uses offscreen rendering (webPreferences.offscreen) on macOS and an attacker has separately gained code execution in the GPU process.
