{"id":"CVE-2026-70598","aliases":["GHSA-pfmc-3mgc-p6fp"],"url":"https://o3.security/vulnerability/CVE-2026-70598","summary":"Electron: Off-screen rendering trusts GPU-supplied geometry over shared-memory size","details":"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.","published":"2026-08-05T15:27:24.392Z","modified":"2026-09-10T08:16:12.688698Z","cvss":{"score":3.9,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:L"},"epss":{"score":0.001,"percentile":0.00997,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"39.8.10"},{"ecosystem":"npm","name":"electron","fixedVersion":"40.9.0"},{"ecosystem":"npm","name":"electron","fixedVersion":"41.2.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"42.0.0-beta.3"}],"fix":{"url":"https://github.com/electron/electron/commit/2c24640e7b0b9c74fe9f44bce0fde138340ff4fb","label":"electron/electron@2c24640"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70598.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-pfmc-3mgc-p6fp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70598"},{"type":"FIX","url":"https://github.com/electron/electron/commit/2c24640e7b0b9c74fe9f44bce0fde138340ff4fb"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T08:16:12.688698Z"}}
