{"id":"CVE-2026-98664","summary":"iio: imu: adis16400: fix unprotected debugfs reads","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: imu: adis16400: fix unprotected debugfs reads\n\nadis16400_serial_number_fops is open coded and never calls\ndebugfs_file_get(), so debugfs_remove_recursive() does not wait for a\nread in progress and unbind frees the iio_dev underneath it.\n\nCommit ae1d37a9bb4b (\"iio: imu: adis16400: use DEFINE_DEBUGFS_ATTRIBUTE\ninstead of DEFINE_SIMPLE_ATTRIBUTE\") converted product_id and\nflash_count to DEFINE_DEBUGFS_ATTRIBUTE, which protects itself, but\nmoved all three files to debugfs_create_file_unsafe().\n\nserial_number prints three registers as \"%.4x-%.4x-%.4x\" and\nDEFINE_DEBUGFS_ATTRIBUTE() formats a single u64, so it cannot be\nconverted without changing what the file returns. adis16475 and\nadis16550 already use debugfs_create_file() for their open coded\nfiles. Use it here too.","modified":"2026-10-20T02:30:55.316699654Z","published":"2026-10-18T15:44:32.940Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98664.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/50e8d70ba0743f88afd7e49f9cebd1841ee677f5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d94787287a113a1326211647d5e0deed1e9de105"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9b4c00f775a915b759b08bfe2c5e806a8301a59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f501302ebb9e1504162351b951fe3ae331c852ab"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98664.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98664"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ae1d37a9bb4bd8d9091a40d153143e99b115ee37"},{"fixed":"e9b4c00f775a915b759b08bfe2c5e806a8301a59"},{"fixed":"50e8d70ba0743f88afd7e49f9cebd1841ee677f5"},{"fixed":"f501302ebb9e1504162351b951fe3ae331c852ab"},{"fixed":"d94787287a113a1326211647d5e0deed1e9de105"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98664.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.8.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98664.json"}}],"schema_version":"1.9.0"}
