It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-34764 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected from 33.0.0-alpha.1; fixed in 39.8.5\n- electron (npm): affected from 33.0.0-alpha.1; fixed in 39.8.5\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.8.5\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.8.5\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.1.0\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.1.0\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-alpha.5\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-alpha.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-34764/ (Markdown: https://insights.sbomify.com/CVE-2026-34764/index.md)","id":"CVE-2026-34764","markdown":"https://insights.sbomify.com/CVE-2026-34764/index.md","name":"CVE-2026-34764","record":{"aliases":["GHSA-8x5q-pvf5-64mp"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Electron framework","requires_auth":"high_privilege","summary":"Electron apps using offscreen shared textures may suffer use-after-free, allowing attackers to cause crashes or execute code via memory corruption.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. From 33.0.0-alpha.1 to before 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, apps that use offscreen rendering with GPU shared textures may be vulnerable to a use-after-free. Under certain conditions, the release() callback provided on a paint event texture can outlive its backing native state, and invoking it after that point dereferences freed memory in the main process, which may lead to a crash or memory corruption. Apps are only affected if they use offscreen rendering with webPreferences.offscreen: { useSharedTexture: true }. Apps that do not enable shared-texture offscreen rendering are not affected. To mitigate this issue, ensure texture.release() is called promptly after the texture has been consumed, before the texture object becomes unreachable. This vulnerability is fixed in 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Electron has a use-after-free in offscreen shared texture release() callback","id":"CVE-2026-34764","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"electronjs:electron","products":["electronjs:electron"],"type":"use_after_free","year":"2026"},"n_packages":8,"n_references":1,"next":{"headline":"Electron named window.open targets not scoped to the opener's browsing context","id":"CVE-2026-34765"},"packages":[{"ecosystem":"npm","fixed":["39.8.5"],"introduced":["33.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["39.8.5"],"introduced":["33.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["40.8.5"],"introduced":["40.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["40.8.5"],"introduced":["40.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["41.1.0"],"introduced":["41.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["41.1.0"],"introduced":["41.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["42.0.0-alpha.5"],"introduced":["42.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-8x5q-pvf5-64mp"},{"ecosystem":"npm","fixed":["42.0.0-alpha.5"],"introduced":["42.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-8x5q-pvf5-64mp"}],"prev":{"headline":"Rack: Rack::Directory info disclosure and DoS via unescaped regex interpolation","id":"CVE-2026-34763"},"products":["electron"],"published":"2026-04-06","related":[{"cvss_score":9.8,"headline":"Chromium Remote Code Execution in electron","id":"CVE-2017-16151","kev_date_added":null,"published":"2018-06-07"},{"cvss_score":8.8,"headline":"Electron protocol handler browser vulnerable to Command Injection","id":"CVE-2018-1000118","kev_date_added":null,"published":"2018-03-07"},{"cvss_score":8.4,"headline":"Electron: Context Isolation bypass via contextBridge VideoFrame transfer","id":"CVE-2026-34780","kev_date_added":null,"published":"2026-04-04"},{"cvss_score":8.3,"headline":"Electron: \u003cwebview\u003e can enable Node.js integration in Web Workers despite embedder restrictions","id":"CVE-2026-102676","kev_date_added":null,"published":"2026-09-29"},{"cvss_score":8.2,"headline":"Electron drops inherited HTML sandbox restrictions for popups opened through OpenURLFromTab","id":"CVE-2026-102673","kev_date_added":null,"published":"2026-09-29"},{"cvss_score":8.2,"headline":"Electron: Windows opened from a sandboxed top-level document do not inherit its sandbox restrictions","id":"CVE-2026-102674","kev_date_added":null,"published":"2026-09-29"},{"cvss_score":8.1,"headline":"Electron: Use-after-free in offscreen child window paint callback","id":"CVE-2026-34774","kev_date_added":null,"published":"2026-04-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-07","vendors":["electron"]},"summary":"Electron apps using offscreen shared textures may suffer use-after-free, allowing attackers to cause crashes or execute code via memory corruption.","url":"https://insights.sbomify.com/CVE-2026-34764/"}
