{"id":"CVE-2026-90404","summary":"platform/chrome: cros_ec_debugfs: Unregister panic notifier","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/chrome: cros_ec_debugfs: Unregister panic notifier\n\ncros_ec_debugfs_probe() registers notifier_panic with the EC panic\nnotifier chain. The remove path tears down debugfs and the console log,\nbut leaves the notifier registered. A later panic notification can call\nback into the removed instance and queue work that accesses released\ndata.\n\nUnregister the panic notifier before tearing down the debugfs and\nconsole log state.\n\nThis issue was found by a static analysis tool.","modified":"2026-09-18T03:48:38.126590602Z","published":"2026-09-17T16:09:33.472Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90404.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/05c1081ae4503e45b934b390350f942db3208892"},{"type":"WEB","url":"https://git.kernel.org/stable/c/56989e2a9c292ff7689603feed41d030301ca636"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a5d3128b06ccfc398c2e456fddebadce52310bd8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e2cbe14361d7cb0b5abd66d87f3afa0e16efde9f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e5954d3031fb55dd31aa59bae477d63c68e941c0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90404.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90404"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d90fa2c64d59f5f151beeef5dbc599784b3391ca"},{"fixed":"56989e2a9c292ff7689603feed41d030301ca636"},{"fixed":"a5d3128b06ccfc398c2e456fddebadce52310bd8"},{"fixed":"e2cbe14361d7cb0b5abd66d87f3afa0e16efde9f"},{"fixed":"05c1081ae4503e45b934b390350f942db3208892"},{"fixed":"e5954d3031fb55dd31aa59bae477d63c68e941c0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90404.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90404.json"}}],"schema_version":"1.9.0"}
