Background
The i2c: i801 package is a component of the Linux Kernel that provides support for the I2C bus controller found on Intel chipsets. It allows communication between various devices connected to the I2C bus. The i801 driver specifically handles the Intel 82801 (ICH) and 6300ESB I2C controllers. This vulnerability affects versions of the Linux Kernel from v3.6 to v4.14.234.
Vulnerability Detail
The vulnerability in the i2c: i801 package involves the generation of an interrupt on bus reset. When a bus reset occurs, the i801 driver should not generate an interrupt, but due to a coding error, it does. This vulnerability could potentially be exploited by an attacker to disrupt the normal operation of the I2C bus and connected devices. The impact and attack plausibility of this vulnerability have not been proven yet.
