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.","state":0,"publishedAt":"2026-08-05T15:27:24.392+00:00","modifiedAt":"2026-08-05T18:15:50.518+00:00","affected":[{"ecosystem":"Vendor product","name":"electron","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"electron\",\n                    \"product\": \"electron\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 39.8.10\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 40.0.0-alpha.1, < 40.9.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 41.0.0-alpha.1, < 41.2.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 42.0.0-alpha.1, < 42.0.0-beta.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:L","score":3.9,"severity":"LOW"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-pfmc-3mgc-p6fp","https://github.com/electron/electron/commit/2c24640e7b0b9c74fe9f44bce0fde138340ff4fb"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-70598","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-70598","identifiers":["CVE-2026-70598"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
