Background
The Kernel package is a fundamental component of the Linux operating system. It provides the core functionality and acts as an interface between the hardware and software layers. The 'host1x' subsystem within the Kernel is responsible for managing the NVIDIA Tegra host1x hardware. This hardware is utilized for various purposes, including graphics processing and display control. Unfortunately, a memory leak vulnerability has been identified in the 'host1x_remove()' function of the 'host1x' subsystem.
Vulnerability Detail
The 'host1x_remove()' function in the 'host1x' subsystem of the Kernel suffers from a memory leak vulnerability. When this function is called to remove the 'host1x' subsystem, it fails to properly release allocated memory, leading to a gradual depletion of system resources. An attacker could potentially exploit this vulnerability to exhaust available memory, resulting in system instability or denial of service. The vulnerability was introduced in Kernel version v4.13 and has been fixed in version v5.10.110.
How To Fix
