Description OSIDB Bzimport 2026-09-24 16:52:05 UTC 
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.
