If component registration fails,\nthe function returns without dropping the link reference.\n\nAlways call snd_hdac_ext_bus_link_put() after the registration attempt so\nthe reference taken during probe is balanced on both success and failure.","modified":"2026-09-18T03:48:34.148230606Z","published":"2026-09-16T10:32:31.253Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89944.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6ad4892c4f5cb437a928a02f5b7d37d496aa9268"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7eef9ae3b4ef782557526dd8ba0c206f028d8c2f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cb6b0b1a9d5a61ef841739d42c6211094e9c8e2c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8ea01a0457080b0cc7c69c430c0ab65d84dc377"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89944.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89944"},{"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":"6bae5ea9498926440ffc883f3dbceb0adc65e492"},{"fixed":"7eef9ae3b4ef782557526dd8ba0c206f028d8c2f"},{"fixed":"e8ea01a0457080b0cc7c69c430c0ab65d84dc377"},{"fixed":"cb6b0b1a9d5a61ef841739d42c6211094e9c8e2c"},{"fixed":"6ad4892c4f5cb437a928a02f5b7d37d496aa9268"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89944.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89944.json"}}],"schema_version":"1.9.0"}
