Electron: Off-screen rendering trusts GPU-supplied geometry over shared-memory size

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.10, 40.9.0, 41.2.1, and 42.0.0-beta.3, offscreen rendering 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. This issue is fixed in 39.8.10, 40.9.0, 41.2.1, and 42.0.0-beta.3.

### Impact In offscreen rendering mode, 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. Apps are only affected if they use offscreen rendering (`webPreferences.offscreen`) and an attacker has separately gained code execution in the GPU process. Apps that do not use offscreen rendering are not affected. ### Workarounds There are no app side workarounds, you must update to a patched version of Electron. ### Fixed Versions * `42.0.0-beta.3` * `41.2.1` * `40.9.0` * `39.8.10` ### For more information If you have any questions or comments about this advisory, email us at [[email protected]](mailto:[email protected])
