Background

The i2c: imx-lpi2c package is a component of the Linux Kernel ecosystem. It provides support for the Inter-Integrated Circuit (I2C) bus on i.MX processors. The I2C bus is a widely used serial communication protocol for connecting low-speed peripherals to microcontrollers and other embedded systems. The imx-lpi2c driver specifically handles the I2C functionality for i.MX processors. This package is vulnerable to a reference leak when the pm_runtime_get_sync function fails.

Vulnerability Detail

The vulnerability in the i2c: imx-lpi2c package occurs when the pm_runtime_get_sync function fails to acquire a reference. This reference leak 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 a gradual depletion of system resources. The impact of this vulnerability depends on the context in which the imx-lpi2c driver is used and the availability of mitigations.
