When the ax25 device is shutting down, the\nax25_dev_device_down() drops the reference count of net_device one\nor zero times depending on if we goto unlock_put or not, which will\ncause memory leak.\n\nIn order to solve the above issue, decrease the reference count of\nnet_device after dev-\u003eax25_ptr is set to null.","modified":"2026-04-16T00:04:58.001047596Z","published":"2024-06-19T13:35:25.406Z","related":["SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2024:3190-1","SUSE-SU-2024:3209-1","SUSE-SU-2024:3483-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38554.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/36e56b1b002bb26440403053f19f9e1a8bc075b2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ec437f9bbae68e9b38115c4c91de995f73f6bad"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8bad3a20a27be8d935f2aae08d3c6e743754944a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/965d940fb7414b310a22666503d2af69459c981b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eef95df9b752699bddecefa851f64858247246e9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38554.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38554"},{"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":"d01ffb9eee4af165d83b08dd73ebdf9fe94a519b"},{"fixed":"3ec437f9bbae68e9b38115c4c91de995f73f6bad"},{"fixed":"965d940fb7414b310a22666503d2af69459c981b"},{"fixed":"8bad3a20a27be8d935f2aae08d3c6e743754944a"},{"fixed":"eef95df9b752699bddecefa851f64858247246e9"},{"fixed":"36e56b1b002bb26440403053f19f9e1a8bc075b2"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"ef0a2a0565727a48f2e36a2c461f8b1e3a61922d"},{"last_affected":"e2b558fe507a1ed4c43db2b0057fc6e41f20a14c"},{"last_affected":"418993bbaafb0cd48f904ba68eeda052d624c821"},{"last_affected":"5ea00fc60676c0eebfa8560ec461209d638bca9d"},{"last_affected":"9af0fd5c4453a44c692be0cbb3724859b75d739b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-38554.json"}}],"schema_version":"1.7.5"}
