  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: Use kvfree instead of kfree in amdgpu_gmc_get_nps_memranges()\n\namdgpu_discovery_get_nps_info() internally allocates memory for ranges\nusing kvcalloc(), which may use vmalloc() for large allocation. Using\nkfree() to release vmalloc memory will lead to a memory corruption.\n\nUse kvfree() to safely handle both kmalloc and vmalloc allocations.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.",
