Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Use kvfree instead of kfree in amdgpu_gmc_get_nps_memranges() amdgpu_discovery_get_nps_info() internally allocates memory for ranges using kvcalloc(), which may use vmalloc() for large allocation. Using kfree() to release vmalloc memory will lead to a memory corruption. Use kvfree() to safely handle both kmalloc and vmalloc allocations. Compile tested only. Issue found using a prototype static analysis tool and code review.
