LowCVSS 3.9Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
Electron is a framework for writing cross-platform desktop applications. 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.
Risk Assessment
A compromised GPU process could disclose memory or crash the app, potentially compromising confidentiality and availability.
Recommendation
Upgrade Electron to version 39.8.10, 40.9.0, 41.2.1, or 42.0.0-beta.3 or later.
