Linux Kernel vulnerability analysis and mitigation
Overview
A memory leak vulnerability was identified in the Linux kernel's drm/amd/pm component. The issue occurs where memory is allocated for gpumetricstable in smuv1304initsmctables() but not properly freed in smuv1304finismctables(). This vulnerability was disclosed on June 18, 2025, affecting the AMD GPU driver's power management component in the Linux kernel (NVD, Wiz).
Technical details
The vulnerability specifically affects the AMD GPU driver's power management component in the Linux kernel. The technical issue involves improper memory management between the initialization and finalization functions of SMC tables, where memory allocated for gpumetricstable is not properly deallocated (Wiz).
Impact
The vulnerability can result in memory leaks in the system, which over time could lead to degraded system performance and potential resource exhaustion (Wiz).
Mitigation and workarounds
The vulnerability has been resolved through a patch that ensures proper memory deallocation in the smuv1304finismctables() function (Wiz).
