Background
The Kernel is a critical component of the Linux operating system that provides core functionality and interfaces with hardware devices. The isp116x driver is responsible for managing USB host controllers. It allows communication between the Kernel and USB devices connected to the system. However, a vulnerability has been discovered in the isp116x driver that could potentially be exploited by attackers.
Vulnerability Detail
The vulnerability in the isp116x driver arises from a failure to check the return value after calling the platform_get_resource() function. This oversight could lead to various security issues, including potential privilege escalation or denial of service attacks. Attackers may be able to manipulate the USB host controller, compromising the integrity and security of the system. The vulnerability has been addressed in Linux Kernel version v4.19.247 by commit 3825db88d8c704e7992b685618a03f82bffcf2ef.
How To Fix

Workaround
If updating the Kernel is not immediately feasible, a temporary workaround can be implemented by disabling the isp116x driver. This can be achieved by blacklisting the driver module or modifying the Kernel configuration to exclude the driver from being loaded. However, it is important to note that this workaround may result in the loss of USB host controller functionality.
Conclusion
In conclusion, the vulnerability in the isp116x driver of the Kernel could potentially be exploited by attackers, leading to security breaches. It is crucial to update the Kernel to the fixed version or apply the temporary workaround to mitigate the risk.
