CVE-2018-16658

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.18.6

Description The issue is related to an information leak in the cdrom ioctl drive status() function in the Linux kernel, which could allow local attackers to read kernel memory. This is due to a cast from unsigned long to int that interferes with bounds checking, leading to potential data exposure. The vulnerability is associated with errors in data processing.

Recommendations For Linux kernel versions prior to 4.18.6, update to version 4.18.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the cdrom ioctl drive status() function to minimize the risk of exploitation.
