CVE-2018-18710 is a vulnerability of currently unknown severity. An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc 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 0.50% chance of exploitation in the next 30 days.
