Memory Leak in AMDGPU Linux Kernel Driver

Publication date: 2026-05-27

Last updated on: 2026-06-16

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix memory leak in amdgpu_ras_init() When amdgpu_nbio_ras_sw_init() fails in amdgpu_ras_init(), the function returns directly without freeing the allocated con structure, leading to a memory leak. Fix this by jumping to the release_con label to properly clean up the allocated memory before returning the error code. Compile tested only. Issue found using a prototype static analysis tool and code review.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's amdgpu driver, specifically in the function amdgpu_ras_init(). When the function amdgpu_nbio_ras_sw_init() fails during initialization, the allocated memory for a structure (con) is not freed properly. This happens because the function returns early without releasing the allocated memory, causing a memory leak.

Impact Analysis

The impact of this vulnerability is a memory leak in the amdgpu driver within the Linux kernel. Over time, this could lead to increased memory usage and potentially degrade system performance or stability if the leaked memory accumulates. However, there is no indication of direct exploitation such as code execution or privilege escalation.

Compliance Impact

The provided information does not specify any impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.
