  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ndrm/amdgpu: fix double free err_addr pointer warnings\nIn amdgpu_umc_bad_page_polling_timeout, the amdgpu_umc_handle_bad_pages\nwill be run many times so that double free err_addr in some special case.\nSo set the err_addr to NULL to avoid the warnings.", "A vulnerability was found in the amdgpu_umc_handle_bad_pages() function in the Linux kernel's amdgpu driver. If the function is called multiple times in quick succession, a double free error can occur because the err_data->err_addr pointer that is being freed is not being set to NULL in between calls. This could lead to memory corruption or crashes." ],
  "statement" : "Red Hat believes this flaw is moderate severity because the permissions necessary to effectively trigger this flaw are high. A user would need to have kernel and driver access to effectively operate the driver and repeatedly trigger the amdgpu_umc_handle_bad_pages() function.",
