Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: validate and share PSP fw_pri_buf copies via psp_copy_fw
Change psp_copy_fw from void to int: return -ENODEV when drm_dev_enter fails, and -EINVAL when the image size is zero or larger than the 1 MiB PSP private buffer.
Replace open-coded memset/memcpy into fw_pri_buf with psp_copy_fw.
