VulnerabilityCVE-2026-114122

Electron: Frame subscription trusts GPU-supplied frame geometry

Apps are only affected if they use `webContents.beginFrameSubscription` and an attacker has separately gained code execution in the GPU process. Apps that do not subscribe to captured frames are not affected.

What to do

GitHub lists first patched versions: electron: 42.11.6; electron: 43.7.3; electron: 44.4.3; electron: 45.0.0-alpha.9. Confirm the affected range and upgrade guidance in the exact advisory.

What happened

### Impact Frame data received from the GPU process for `webContents.beginFrameSubscription` 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 the captured frame images, disclosing memory or crashing the app.

Apps are only affected if they use `webContents.beginFrameSubscription` and an attacker has separately gained code execution in the GPU process. Apps that do not subscribe to captured frames are not affected.

### Workarounds There are no app side workarounds, you must update to a patched version of Electron.

### Fixed Versions * `45.0.0-alpha.9` * `44.4.3` * `43.7.3` * `42.11.6`

About this data

This record was ingested from a data source. Retrieved: Oct 26, 2026, 19:40 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
