Also,\nswitch to unsigned int and remove useless check for negative 'opt'\nin ROSE_IDLE case.","modified":"2026-04-02T12:45:11.746766Z","published":"2025-02-27T02:07:23.746Z","related":["SUSE-SU-2025:01919-1","SUSE-SU-2025:1177-1","SUSE-SU-2025:1178-1","SUSE-SU-2025:1180-1","SUSE-SU-2025:20190-1","SUSE-SU-2025:20192-1","SUSE-SU-2025:20260-1","SUSE-SU-2025:20270-1","USN-7521-2"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21711.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/352daa50946c3bbb662432e8daf54d6760796589"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4bdd449977e2364a53d0b2a5427e71beb1cd702d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9bdee49ad6bbd26ab5e13cc6731e54fb1b6c1dca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b8583b54455cbec2fc038fa32b6700890b369815"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d08f4074f9c69f7e95502587eb1b258a965ba7f0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d640627663bfe7d8963c7615316d7d4ef60f3b0b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e5338930a29d0ab2a5af402f5f664aeba0d1a676"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00028.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21711.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-21711"},{"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":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2"},{"fixed":"4bdd449977e2364a53d0b2a5427e71beb1cd702d"},{"fixed":"b8583b54455cbec2fc038fa32b6700890b369815"},{"fixed":"9bdee49ad6bbd26ab5e13cc6731e54fb1b6c1dca"},{"fixed":"352daa50946c3bbb662432e8daf54d6760796589"},{"fixed":"d08f4074f9c69f7e95502587eb1b258a965ba7f0"},{"fixed":"e5338930a29d0ab2a5af402f5f664aeba0d1a676"},{"fixed":"d640627663bfe7d8963c7615316d7d4ef60f3b0b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-21711.json"}}],"schema_version":"1.7.5"}
