In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/amdgpu: Skip KFD mapping clear before initialization<\/p>\n
amdgpu_amdkfd_clear_kfd_mapping() assumes that a non-NULL kfd_dev
\nhas a fully populated node array. This is not true when KFD device
\ninitialization fails after probe.<\/p>\n
For example, kgd2kfd_device_init() sets num_nodes before checking
\nPCIe atomics support. On Polaris systems without the required atomics,
\nit returns before allocating nodes[0], but the kfd_dev remains attached
\nto the amdgpu device. A later GPU reset then dereferences nodes[0]->id.<\/p>\n
Require the authoritative KFD initialization flag before walking the
\nnode array, matching the existing KFD reset and teardown paths.<\/p>\n
