What is CVE-2025-21842?

A memory management flaw exists in the Linux kernel affecting AMD graphics processing units (GPUs). Specifically, an improper memory deallocation occurs during the initialization of a user queue, leading to potential errors due to the mishandling of a gtt bo pointer. The function 'amdgpu_amdkfd_free_gtt_mem' expects a double pointer, but it may encounter issues when a single pointer is provided, resulting in improper memory access that could jeopardize system stability.
