Background

The Kernel is a critical component of the Linux operating system that provides core functionalities and manages system resources. It acts as an interface between the hardware and software layers, allowing applications to communicate with the underlying hardware. The imu_fmt module in the Kernel's media staging/intel-ipu3 subsystem is responsible for handling image format operations for Intel Image Processing Units (IPU3). This vulnerability specifically affects the imu_fmt module and can lead to a memory leak.

Vulnerability Detail

The memory leak vulnerability in imu_fmt module of the Kernel's media staging/intel-ipu3 subsystem allows an attacker to cause a continuous loss of memory resources. By exploiting this vulnerability, an attacker can exhaust available memory, leading to system instability, performance degradation, and potential denial-of-service (DoS) conditions. The vulnerability was introduced in version v5.2 of the Linux Kernel and has been fixed in version v5.12.3.

How To Fix
