The Linux 5.3 kernel includes accepted<\/a><\/noindex> modifications adding extra protection for ioctl calls related to the floppy driver, which itself is marked as orphaned
\n(\"orphaned\"), implying the cessation of its testing.<\/p>\n

The driver is considered outdated, as it is difficult to find functional hardware for its testing \u2014 all current external drives typically use the USB interface. Moreover, the removal of the driver from the kernel is hindered by the fact that floppy disk controllers are still emulated in virtualization systems. Therefore, the driver remains in the kernel for now, but its proper functionality is not guaranteed.<\/p>\n

Additionally, the floppy driver has been closed<\/a><\/noindex> vulnerability<\/a><\/noindex> (CVE-2019-14283<\/a><\/noindex>), which allows an unprivileged user, capable of inserting their own floppy disk, to read data from memory areas outside the bounds of the copy buffer (for example, adjacent areas may contain residual data from the disk cache and input buffer). On one hand, the vulnerability remains relevant since the floppy driver is automatically loaded when a corresponding emulated controller is present in virtualization systems (for instance, it is used by default in QEMU), but on the other hand, to exploit the issue, a specially crafted floppy disk image prepared by an attacker must be connected.<\/p>\n
