Prior to versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9, frame data received from the GPU process for macOS offscreen rendering was not fully validated by the main process. An attacker who had separately gained code execution in the GPU process could provide inconsistent frame geometry and cause the main process to read out-of-bounds memory while producing paint event images, disclosing memory or crashing the application. This issue is fixed in versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-125"],"references":["https://github.com/electron/electron/commit/24d8dbc661c6a109476ae59e9a2740b35d005cf4","https://github.com/electron/electron/commit/64ae597deda8956037387b439e6361f0fe936c86","https://github.com/electron/electron/commit/8d48be150c3fd53b0d02854124bdb7858598799c","https://github.com/electron/electron/commit/d496507ffa1693edaa704a4be130fbcb8ecb4ada","https://github.com/electron/electron/commit/d7f87070a8d738e561245d1ade4d6fbb082db80a"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-114124","score":0.00185,"percentile":0.08066,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-h3v5-h239-pg29","url":"https://osv.dev/vulnerability/GHSA-h3v5-h239-pg29","summary":"Electron: Off-screen rendering on macOS trusts GPU-supplied frame geometry","modified":"2026-10-22T17:00:04.188728824Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<42.11.6"],"fixed":["42.11.6"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=43.0.0-alpha.1 <43.7.3"],"fixed":["43.7.3"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=44.0.0-alpha.1 <44.4.3"],"fixed":["44.4.3"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=45.0.0-alpha.1 <45.0.0-alpha.9"],"fixed":["45.0.0-alpha.9"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
