CVE-2018-18710 kernel: Information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c
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. This is similar to CVE-2018-10940 and CVE-2018-16658.

CVE-2018-10940 kernel: incorrect memory bounds check in drivers/cdrom/cdrom.c
The cdrom_ioctl_media_changed function in drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6 allows local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory.
