Name of the Vulnerable Software and Affected Versions

Description
The issue is related to the

For Linux kernel versions prior to 4.17, update to version 4.17 or later to resolve the issue. As a temporary workaround, consider restricting access to AF IRDA sockets to minimize the risk of exploitation.
