{"id":"CVE-2018-16658","details":"An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940.","modified":"2026-03-15T22:19:25.997385Z","published":"2018-09-07T14:29:03.523Z","related":["SUSE-SU-2018:2775-1","SUSE-SU-2018:2776-1","SUSE-SU-2018:2858-1","SUSE-SU-2018:2862-1","SUSE-SU-2018:2879-1","SUSE-SU-2018:2907-1","SUSE-SU-2018:2908-1","SUSE-SU-2018:2908-2","SUSE-SU-2018:2980-1","SUSE-SU-2018:2981-1","SUSE-SU-2018:3083-1","SUSE-SU-2018:3084-1","SUSE-SU-2018:3088-1","SUSE-SU-2018:3961-1"],"references":[{"type":"ADVISORY","url":"https://usn.ubuntu.com/3797-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3797-2/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3820-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3822-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3822-2/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4308"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/105334"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4154"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2029"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2043"},{"type":"ADVISORY","url":"https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.18.6"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3820-3/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3820-2/"},{"type":"FIX","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8f3fafc9c2f0ece10832c25f7ffcb07c97a32ad4"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/8f3fafc9c2f0ece10832c25f7ffcb07c97a32ad4"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"4.18.6"}]},{"events":[{"introduced":"0"},{"last_affected":"12.04"}]},{"events":[{"introduced":"0"},{"last_affected":"14.04"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-16658.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H"}]}
