{"id":"CVE-2018-7273","details":"In the Linux kernel through 4.15.4, the floppy driver reveals the addresses of kernel functions and global variables using printk calls within the function show_floppy in drivers/block/floppy.c. An attacker can read this information from dmesg and use the addresses to find the locations of kernel code and data and bypass kernel security protections such as KASLR.","modified":"2026-03-14T14:03:26.048435Z","published":"2018-02-21T00:29:00.333Z","references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/103088"},{"type":"ADVISORY","url":"https://lkml.org/lkml/2018/2/20/669"},{"type":"EVIDENCE","url":"https://www.exploit-db.com/exploits/44325/"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.15.4"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-7273.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:H/I:N/A:N"}]}
