Background
The Kernel package is a fundamental component of the Linux operating system. It provides the core functionality and interfaces for various hardware devices and software components. The pxa3xx-gcu driver is responsible for managing the graphics processing unit (GPU) on PXA3xx-based systems. This vulnerability specifically affects the resource release mechanism in the pxa3xx_gcu_probe/remove() functions of the driver.
Vulnerability Detail
The vulnerability in the pxa3xx-gcu driver arises from incorrect resource release in the pxa3xx_gcu_probe/remove() functions. When the driver is probed or removed, certain resources are not properly released, leading to potential resource leaks and other related issues. Exploiting this vulnerability could result in system instability, resource exhaustion, or privilege escalation.
How To Fix
No fixed version is published for this vulnerability.
