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. GHSA-pfmc-3mgc-p6fp covers the same issue on the other capture paths.\n\nApps are only affected if they use offscreen rendering (`webPreferences.offscreen`) on macOS and an attacker has separately gained code execution in the GPU process. Apps that do not use offscreen rendering are not affected.\n\n### Workarounds\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n* `45.0.0-alpha.9`\n* `44.4.3`\n* `43.7.3`\n* `42.11.6`\n\n### For more information\nIf you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)","state":0,"publishedAt":"2026-10-22T16:44:33+00:00","modifiedAt":"2026-10-22T17:00:04.1887288+00:00","affected":[{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"42.11.6"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"43.0.0-alpha.1"},{"kind":"fixed","version":"43.7.3"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"44.0.0-alpha.1"},{"kind":"fixed","version":"44.4.3"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"45.0.0-alpha.1"},{"kind":"fixed","version":"45.0.0-alpha.9"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:L","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-h3v5-h239-pg29","https://nvd.nist.gov/vuln/detail/CVE-2026-114124","https://github.com/electron/electron/pull/54047","https://github.com/electron/electron/pull/54038","https://github.com/electron/electron/pull/54037","https://github.com/electron/electron/pull/54036","https://github.com/electron/electron/pull/54033","https://github.com/electron/electron/commit/d7f87070a8d738e561245d1ade4d6fbb082db80a","https://github.com/electron/electron/commit/d496507ffa1693edaa704a4be130fbcb8ecb4ada","https://github.com/electron/electron/commit/8d48be150c3fd53b0d02854124bdb7858598799c","https://github.com/electron/electron/commit/64ae597deda8956037387b439e6361f0fe936c86","https://github.com/electron/electron/commit/24d8dbc661c6a109476ae59e9a2740b35d005cf4","https://github.com/electron/electron/releases/tag/v42.11.6","https://github.com/electron/electron/releases/tag/v43.7.3","https://github.com/electron/electron/releases/tag/v44.4.3","https://github.com/electron/electron/releases/tag/v45.0.0-alpha.9","https://github.com/electron/electron"],"sourceUrl":"https://github.com/advisories/GHSA-h3v5-h239-pg29","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-h3v5-h239-pg29","identifiers":["GHSA-h3v5-h239-pg29","CVE-2026-114124"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
