Published Sep 7, 2018 CVSS 3.0 · 6.1 Medium EPSS < 1% KEV · Not listed
Description
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.
