The problem is that on 32bit systems if they're both greater than\nUINT_MAX - 16 then the check does work as intended because of an integer\noverflow.","modified":"2026-04-02T12:45:20.505384Z","published":"2025-04-16T14:12:29.886Z","related":["MGASA-2025-0142","MGASA-2025-0146","SUSE-SU-2025:01614-1","SUSE-SU-2025:01707-1","SUSE-SU-2025:01919-1","SUSE-SU-2025:01951-1","SUSE-SU-2025:01964-1","SUSE-SU-2025:01967-1","SUSE-SU-2025:20343-1","SUSE-SU-2025:20344-1","SUSE-SU-2025:20354-1","SUSE-SU-2025:20355-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22080.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/201a2bdda13b619c4927700ffe47d387a30ced50"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6bb81b94f7a9cba6bde9a905cef52a65317a8b04"},{"type":"WEB","url":"https://git.kernel.org/stable/c/85615aa442830027923fc690390fa74d17b36ae1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b9982065b82b4177ba3a7a72ce18c84921f7494d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6d44b1aa46d317e52c21fb9314cfb20dd69e7b0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22080.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22080"},{"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":"60ce8dfde03558bfc290cd915c60fa243ba2ae84"},{"fixed":"f6d44b1aa46d317e52c21fb9314cfb20dd69e7b0"},{"fixed":"201a2bdda13b619c4927700ffe47d387a30ced50"},{"fixed":"85615aa442830027923fc690390fa74d17b36ae1"},{"fixed":"b9982065b82b4177ba3a7a72ce18c84921f7494d"},{"fixed":"6bb81b94f7a9cba6bde9a905cef52a65317a8b04"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22080.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
