Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.12.4
Description: The issue is related to a driver error in the Linux kernel, specifically in the i8042 controller driver. It allows attackers to cause a denial of service, resulting in a system crash due to a NULL pointer dereference. There is also a possibility of unspecified other impact. The problem arises because the port->exists value can change after it has been validated.
Recommendations: For versions prior to 4.12.4, update to version 4.12.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable driver to minimize the risk of exploitation.
