Background
The drm/amd/amdgpu package is a component of the Linux Kernel that provides support for AMD GPUs. It is responsible for managing the graphics hardware and enabling the display functionality. The package is widely used in Linux-based systems that utilize AMD graphics cards. However, a potential memory leak vulnerability has been identified in this package.
Vulnerability Detail
The vulnerability in the drm/amd/amdgpu package could lead to a memory leak. A memory leak occurs when a program fails to release memory that is no longer needed, resulting in a gradual reduction in available memory. This can eventually lead to system instability or crashes. The vulnerability has the potential to be exploited by an attacker to exhaust system resources and disrupt the normal functioning of the affected system. The vulnerability has been fixed in Linux Kernel version v5.10.84 by commit c746945fb6bcbe3863c9ea6369c7ef376e38e5eb.
How To Fix
No fixed version is published for this vulnerability.
To fix the vulnerability, it is recommended to update the Linux Kernel to version v5.10.84 or later. This can be done by obtaining the updated kernel source code from the official Linux Kernel repository (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/) and compiling it according to the provided instructions. Once the updated kernel is installed, the vulnerability should be mitigated.
