Memory Allocation Failure in Linux drm/msm/a6xx GPU Driver

Publication date: 2025-12-30

Last updated on: 2025-12-30

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Replace kcalloc() with kvzalloc() In order to reduce chance of allocation failure while capturing a6xx gpu state, use kvzalloc() instead of kcalloc() in state_kcalloc(). Indirectly, this patch helps to fix leaking memory allocated for gmu_debug object. Patchwork: https://patchwork.freedesktop.org/patch/505074/

Executive Summary

This vulnerability is related to the Linux kernel's drm/msm/a6xx driver where the function state_kcalloc() used kcalloc() for memory allocation. The issue was that kcalloc() could fail to allocate memory, leading to potential memory leaks, specifically for the gmu_debug object. The fix replaced kcalloc() with kvzalloc(), which reduces the chance of allocation failure and helps prevent leaking memory.

Impact Analysis

The vulnerability can lead to leaking memory allocated for the gmu_debug object in the Linux kernel's a6xx GPU driver. This memory leak could degrade system performance or stability over time due to inefficient memory usage.
