What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Public exploit evidence

Original source description

Read the full publisher description

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.
