Background
The sc16is7xx package is a Linux Kernel module that provides support for the SC16IS7xx family of UART devices. These devices are commonly used for serial communication in embedded systems. The package allows users to interface with these UART devices and perform various operations such as data transmission and reception. However, a vulnerability has been discovered in the package that leads to incorrect data being transmitted.
Vulnerability Detail
The vulnerability in the sc16is7xx package arises from a flaw in the data transmission mechanism. When data is sent through the UART device, it may get corrupted or altered during the transmission process. This can result in incorrect data being received by the intended recipient. The impact of this vulnerability can vary depending on the specific use case of the affected system. In some scenarios, it may lead to data corruption or misinterpretation, potentially causing functional or security issues. The vulnerability was introduced in version v5.8 of the Linux Kernel and has been fixed in version v5.10.103.
How To Fix
