Background
The i2c: imx-lpi2c package is a component of the Linux Kernel ecosystem. It provides support for the I2C bus on the i.MX platform. The I2C bus is a widely used serial communication protocol for connecting various devices in embedded systems. The imx-lpi2c driver is responsible for managing the I2C interface on i.MX SoCs. It allows communication with I2C devices, such as sensors, EEPROMs, and other peripherals. However, a vulnerability has been discovered in this package that can lead to a reference leak when pm_runtime_get_sync fails.
Vulnerability Detail
The vulnerability in the i2c: imx-lpi2c package occurs when pm_runtime_get_sync fails. This can result in a reference leak, which can lead to resource exhaustion and potential denial-of-service attacks. An attacker could exploit this vulnerability by repeatedly triggering the failure of pm_runtime_get_sync, causing the system to exhaust its resources and become unresponsive. The impact of this vulnerability can vary depending on the specific use case and system configuration. It is important to note that the actual attack plausibility and impact have not been proven.
