Background
The Kernel is a crucial component of the Linux operating system, responsible for managing system resources and providing an interface between hardware and software. The rga_probe function in the media subsystem of the Kernel is used to probe and initialize the Rockchip Graphics Accelerator (RGA) hardware. The RGA is responsible for accelerating various media operations, such as image and video processing. However, a vulnerability has been discovered in the rga_probe function that could lead to a memory leak.
Vulnerability Detail
The vulnerability in rga_probe arises from a possible memory leak. When the function is called, it may allocate memory but fail to deallocate it properly under certain conditions. This can result in a gradual depletion of available memory resources, potentially leading to system instability or denial of service. An attacker may be able to exploit this vulnerability to exhaust system memory and cause a system crash or other adverse effects. The vulnerability has been addressed in Linux Kernel version v5.18.3 by commit 1cdc768468c25d6b10ab83ec1efd4a8554532d69.
