Detailsinfo

A vulnerability was found in Electron up to 42.11.5/43.7.2/44.4.2/45.0.0-alpha.8. It has been rated as problematic. This issue affects the function webContents.beginFrameSubscription of the component GPU Process. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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 webContents.beginFrameSubscription was not fully validated by the main process. An attacker who had separately gained code execution in the GPU process could supply inconsistent frame geometry and cause the main process to read out-of-bounds memory while producing captured frame 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.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-114122 since 10/20/2026. The exploitation is known to be easy. An attack has to be approached locally. Technical details are known, but no exploit is available.

Upgrading to version 42.11.6, 43.7.3, 44.4.3 or 45.0.0-alpha.9 eliminates this vulnerability.
