Last modified

CVE-2018-16658 is a vulnerability of currently unknown severity. An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. EPSS estimates a 0.55% chance of exploitation in the next 30 days.
