Background
The drm/amd/pm package is a component of the Linux Kernel that handles power management for AMD GPUs. It provides functionality for controlling the power states and performance levels of the graphics card. The package is responsible for managing the GPU metrics table, which is used to collect and store performance data. However, a vulnerability has been discovered in the package that can lead to a memory leak in the gpu_metrics_table data structure.
Vulnerability Detail
The vulnerability in the drm/amd/pm package can result in a memory leak in the gpu_metrics_table. This can occur when the package fails to properly release memory allocated for the table, leading to a gradual depletion of system resources. An attacker could potentially exploit this vulnerability to exhaust available memory, causing system instability or denial of service. The vulnerability was introduced in version v5.10 of the Linux Kernel and has been fixed in version v5.10.88.
How To Fix
