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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-70598)\n\nAffected packages:\n\n- `electron < 39.8.10`\n- `electron >= 40.0.0-alpha.1, < 40.9.0`\n- `electron >= 41.0.0-alpha.1, < 41.2.1`\n- `electron >= 42.0.0-alpha.1, < 42.0.0-beta.3`\n\nPatched in:\n\n- `electron 39.8.10`\n- `electron 40.9.0`\n- `electron 41.2.1`\n- `electron 42.0.0-beta.3`\n\nSource: https://github.com/advisories/GHSA-pfmc-3mgc-p6fp","depth":"sunlit","depthScore":21,"depthScoreParts":{"impact":21.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
