VetorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel versions 5.0.x up to, excluding 5.0.17
Description: A flaw in the Linux kernel's freescale hypervisor manager implementation allows an attacker to crash the system, corrupt memory, or create other adverse security effects. This is due to incorrect validation and use of a parameter passed to an ioctl in size calculations for the page size calculation.
Recommendations: For Linux kernel versions 5.0.x up to, excluding 5.0.17, consider updating to version 5.0.17 or later to resolve the issue. As a temporary workaround, restrict access to the ioctl to minimize the risk of exploitation.
