{"id":"UBUNTU-CVE-2025-59466","details":"We have identified a bug in Node.js error handling where \"Maximum call stack size exceeded\" errors become uncatchable when `async_hooks.createHook()` is enabled. Instead of reaching `process.on('uncaughtException')`, the process terminates, making the crash unrecoverable. Applications that rely on `AsyncLocalStorage` (v22, v20) or `async_hooks.createHook()` (v24, v22, v20) become vulnerable to denial-of-service crashes triggered by deep recursion under specific conditions.","modified":"2026-02-03T09:08:25.874825Z","published":"2026-01-20T21:16:00Z","upstream":["CVE-2025-59466"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-59466"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-59466"},{"type":"REPORT","url":"https://nodejs.org/en/blog/vulnerability/december-2025-security-releases#uncatchable-maximum-call-stack-size-exceeded-error-on-nodejs-via-async_hooks-leads-to-process-crashes-bypassing-error-handlers-cve-2025-59466---medium"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/nodejs@0.10.25~dfsg2-2ubuntu1.2+esm2?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.15~dfsg1-4","0.10.21~dfsg1-1","0.10.22~dfsg1-2","0.10.23~dfsg1-1","0.10.23~dfsg1-2","0.10.23~dfsg1-3","0.10.24~dfsg1-1","0.10.25~dfsg2-2","0.10.25~dfsg2-2ubuntu1","0.10.25~dfsg2-2ubuntu1.2","0.10.25~dfsg2-2ubuntu1.2+esm1","0.10.25~dfsg2-2ubuntu1.2+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"nodejs","binary_version":"0.10.25~dfsg2-2ubuntu1.2+esm2"},{"binary_name":"nodejs-dev","binary_version":"0.10.25~dfsg2-2ubuntu1.2+esm2"},{"binary_name":"nodejs-legacy","binary_version":"0.10.25~dfsg2-2ubuntu1.2+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59466.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/nodejs@4.2.6~dfsg-1ubuntu4.2+esm3?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.25~dfsg2-2ubuntu1","4.2.2~dfsg-1","4.2.3~dfsg-1","4.2.4~dfsg-1ubuntu1","4.2.4~dfsg-2","4.2.6~dfsg-1ubuntu1","4.2.6~dfsg-1ubuntu4","4.2.6~dfsg-1ubuntu4.1","4.2.6~dfsg-1ubuntu4.2","4.2.6~dfsg-1ubuntu4.2+esm1","4.2.6~dfsg-1ubuntu4.2+esm2","4.2.6~dfsg-1ubuntu4.2+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"nodejs","binary_version":"4.2.6~dfsg-1ubuntu4.2+esm3"},{"binary_name":"nodejs-dev","binary_version":"4.2.6~dfsg-1ubuntu4.2+esm3"},{"binary_name":"nodejs-legacy","binary_version":"4.2.6~dfsg-1ubuntu4.2+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59466.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/nodejs@8.10.0~dfsg-2ubuntu0.4+esm6?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.11.4~dfsg-1ubuntu1","6.11.4~dfsg-1ubuntu2","6.12.0~dfsg-1ubuntu1","6.12.0~dfsg-2ubuntu1","6.12.0~dfsg-2ubuntu2","8.10.0~dfsg-2","8.10.0~dfsg-2ubuntu0.2","8.10.0~dfsg-2ubuntu0.3","8.10.0~dfsg-2ubuntu0.4","8.10.0~dfsg-2ubuntu0.4+esm1","8.10.0~dfsg-2ubuntu0.4+esm2","8.10.0~dfsg-2ubuntu0.4+esm3","8.10.0~dfsg-2ubuntu0.4+esm4","8.10.0~dfsg-2ubuntu0.4+esm5","8.10.0~dfsg-2ubuntu0.4+esm6"],"ecosystem_specific":{"binaries":[{"binary_name":"nodejs","binary_version":"8.10.0~dfsg-2ubuntu0.4+esm6"},{"binary_name":"nodejs-dev","binary_version":"8.10.0~dfsg-2ubuntu0.4+esm6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59466.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/nodejs@10.19.0~dfsg-3ubuntu1.6+esm2?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.15.2~dfsg-2ubuntu1","10.17.0~dfsg-2ubuntu4","10.17.0~dfsg-2ubuntu6","10.19.0~dfsg-3ubuntu1","10.19.0~dfsg-3ubuntu1.1","10.19.0~dfsg-3ubuntu1.2","10.19.0~dfsg-3ubuntu1.3","10.19.0~dfsg-3ubuntu1.5","10.19.0~dfsg-3ubuntu1.6","10.19.0~dfsg-3ubuntu1.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libnode-dev","binary_version":"10.19.0~dfsg-3ubuntu1.6+esm2"},{"binary_name":"libnode64","binary_version":"10.19.0~dfsg-3ubuntu1.6+esm2"},{"binary_name":"nodejs","binary_version":"10.19.0~dfsg-3ubuntu1.6+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59466.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/nodejs@12.22.9~dfsg-1ubuntu3.6+esm2?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.22.5~dfsg-5ubuntu1","12.22.7~dfsg-2ubuntu1","12.22.7~dfsg-2ubuntu3","12.22.9~dfsg-1ubuntu2","12.22.9~dfsg-1ubuntu3","12.22.9~dfsg-1ubuntu3.1","12.22.9~dfsg-1ubuntu3.2","12.22.9~dfsg-1ubuntu3.3","12.22.9~dfsg-1ubuntu3.4","12.22.9~dfsg-1ubuntu3.5","12.22.9~dfsg-1ubuntu3.6","12.22.9~dfsg-1ubuntu3.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libnode-dev","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"},{"binary_name":"libnode72","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"},{"binary_name":"nodejs","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"}]},"database_specific"
