CVE-2019-14284

21
FAUCET Score

CVE-2019-14284 is a denial-of-service vulnerability in the Linux kernel's floppy disk driver (drivers/block/floppy.c) affecting versions prior to 5.2.3. An unprivileged local user can trigger a division-by-zero error by sending specific ioctl commands, even without a physical floppy disk, leading to system instability. This vulnerability is rated Medium severity (CVSS 6.2) due to its local attack vector and the potential for a complete system denial of service. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
