CVE-2018-7755

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discove...

CVE-2018-7755

CVE-2018-7755 affects the Linux kernel floppy driver: the fd_locked_ioctl path in drivers/block/floppy.c copies a kernel pointer to user memory in response to FDGETPRM, enabling a local attacker with floppy access to discover kernel code/data locations and bypass KASLR. The issue is in kernel ver...

CVE-2018-7273

CVE-2018-7273 affects the Linux kernel floppy driver. The show_floppy path in drivers/block/floppy.c prints kernel addresses via printk, enabling local attackers to read addresses from dmesg and locate kernel code/data, potentially bypassing KASLR. The vulnerability is described for Linux kernels...
