    CVE-2018-16658

    Published: 7 Sept 2018Last Modified: 15 Mar 2026

    Summary:

    Details: 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. This is similar to CVE-2018-10940.
