CVE-2024-56697

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix the memory allocation issue in amdgpu_discovery_get_nps_info() Fix two issues with memory allocation in amdgpu_discovery_get_nps_info() for mem_ranges: - Add a check for allocation failure to avoid dereferencing a null pointer. - As suggested by Christophe, use kvcalloc() for memory allocation, which checks for multiplication overflow. Additionally, assign the output parameters nps_type and range_cnt after the kvcalloc() call to prevent modifying the output parameters in case of an error return.
