A compromised GPU process could cause the main process to read out-of-bounds memory while producing the captured frame images, disclosing memory or crashing the app.\n\nApps are only affected if they use `webContents.beginFrameSubscription` and an attacker has separately gained code execution in the GPU process. Apps that do not subscribe to captured frames 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)","affected":[{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"42.11.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-3qxv-5xgr-q7w9/GHSA-3qxv-5xgr-q7w9.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"43.0.0-alpha.1"},{"fixed":"43.7.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-3qxv-5xgr-q7w9/GHSA-3qxv-5xgr-q7w9.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"44.0.0-alpha.1"},{"fixed":"44.4.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-3qxv-5xgr-q7w9/GHSA-3qxv-5xgr-q7w9.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"45.0.0-alpha.1"},{"fixed":"45.0.0-alpha.9"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-3qxv-5xgr-q7w9/GHSA-3qxv-5xgr-q7w9.json"}}],"references":[{"type":"WEB","url":"https://github.com/electron/electron/security/advisories/GHSA-3qxv-5xgr-q7w9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114122"},{"type":"WEB","url":"https://github.com/electron/electron/pull/54047"},{"type":"WEB","url":"https://github.com/electron/electron/pull/54038"},{"type":"WEB","url":"https://github.com/electron/electron/pull/54037"},{"type":"WEB","url":"https://github.com/electron/electron/pull/54036"},{"type":"WEB","url":"https://github.com/electron/electron/pull/54033"},{"type":"WEB","url":"https://github.com/electron/electron/commit/d7f87070a8d738e561245d1ade4d6fbb082db80a"},{"type":"WEB","url":"https://github.com/electron/electron/commit/d496507ffa1693edaa704a4be130fbcb8ecb4ada"},{"type":"WEB","url":"https://github.com/electron/electron/commit/8d48be150c3fd53b0d02854124bdb7858598799c"},{"type":"WEB","url":"https://github.com/electron/electron/commit/64ae597deda8956037387b439e6361f0fe936c86"},{"type":"WEB","url":"https://github.com/electron/electron/commit/24d8dbc661c6a109476ae59e9a2740b35d005cf4"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v42.11.6"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v43.7.3"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v44.4.3"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v45.0.0-alpha.9"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"database_specific":{"cwe_ids":["CWE-125"],"github_reviewed":true,"github_reviewed_at":"2026-10-22T16:46:06Z","nvd_published_at":"2026-10-21T17:18:25Z","severity":"LOW"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:L"}]}
