{"id":"CVE-2026-64492","summary":"iio: temperature: tmp006: use devm_iio_trigger_register","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: temperature: tmp006: use devm_iio_trigger_register\n\ntmp006_probe() allocates the DRDY trigger with devm_iio_trigger_alloc()\nbut registers it with plain iio_trigger_register(). The driver has no\n.remove() callback, so on module unload the trigger stays in the global\ntrigger list while its memory is freed by devm, leaving a dangling\nentry.\n\nSwitch to devm_iio_trigger_register() so the registration is undone in\nthe same devm scope as the allocation.","modified":"2026-07-27T04:02:41.303147502Z","published":"2026-07-25T08:51:50.313Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64492.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3c5eed894efd93d68d7f6a359a81ddef0e928774"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a4f8491da9563ba6eb77969ac26fc7052114c476"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d90f868f56a16e10eedc6552f48d99dff4d275b7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64492.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64492"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"91f75ccf9f032e17cde54f0c01eae2da4f067bc5"},{"fixed":"a4f8491da9563ba6eb77969ac26fc7052114c476"},{"fixed":"d90f868f56a16e10eedc6552f48d99dff4d275b7"},{"fixed":"3c5eed894efd93d68d7f6a359a81ddef0e928774"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64492.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64492.json"}}],"schema_version":"1.7.5"}
