CVE-2019-14283 (GCVE-0-2019-14283)

Vulnerability from cvelistv5 – Published: 2019-07-26 12:24 – Updated: 2024-08-05 00:12
VLAI
Summary
In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default.
