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-2026-114122 (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, when processing a captured video frame whose content_rect and coded_size fields are not validated against the actual shared-memory mapping size before pixel data is read. An attacker with code execution in the GPU process can supply a malformed frame layout over Mojo, causing the renderer to read memory outside the shared-memory region and potentially disclose contents or crash the renderer process.
Note: This is only exploitable if the app uses webContents.beginFrameSubscription and an attacker has separately gained code execution in the GPU process.
