{"id":"CVE-2019-14284","details":"In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setup_format_params division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted. NOTE: QEMU creates the floppy device by default.","modified":"2026-03-12T22:59:04.703100Z","published":"2019-07-26T13:15:13.113Z","related":["SUSE-SU-2019:14157-1","SUSE-SU-2019:2068-1","SUSE-SU-2019:2069-1","SUSE-SU-2019:2070-1","SUSE-SU-2019:2071-1","SUSE-SU-2019:2072-1","SUSE-SU-2019:2073-1","SUSE-SU-2019:2262-1","SUSE-SU-2019:2263-1","SUSE-SU-2019:2299-1","SUSE-SU-2019:2430-1","SUSE-SU-2019:2450-1","openSUSE-SU-2019:1923-1","openSUSE-SU-2019:1924-1"],"references":[{"type":"WEB","url":"https://seclists.org/bugtraq/2019/Aug/18"},{"type":"WEB","url":"https://usn.ubuntu.com/4116-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4117-1/"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html"},{"type":"WEB","url":"http://packetstormsecurity.com/files/154408/Kernel-Live-Patch-Security-Notice-LSN-0055-1.html"},{"type":"WEB","url":"https://usn.ubuntu.com/4115-1/"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2019/08/msg00016.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2019/08/msg00017.html"},{"type":"WEB","url":"https://seclists.org/bugtraq/2019/Aug/26"},{"type":"WEB","url":"https://usn.ubuntu.com/4118-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4114-1/"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html"},{"type":"WEB","url":"http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html"},{"type":"WEB","url":"http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html"},{"type":"WEB","url":"https://seclists.org/bugtraq/2019/Aug/13"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4495"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190905-0002/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4497"},{"type":"ADVISORY","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.3"},{"type":"FIX","url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f3554aeb991214cbfafd17d55e2bfddb50282e32"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/f3554aeb991214cbfafd17d55e2bfddb50282e32"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-14284.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"5.2.3"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
