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/

Can you explain this vulnerability to me?

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.


How can this vulnerability impact me? :

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.
