Commit
7ffeb2fc2670 ("x86/sev: Document requirement for linear mapping of guest request buffers")
added a check that requires the guest request buffers to be in the linear
mapping. The get_derived_key() function was passing a buffer that was
allocated on the stack, resulting in the call to snp_send_guest_request()
returning an error.
Update the get_derived_key() function to use an allocated buffer instead
of a stack buffer.
Fixes: 7ffeb2fc2670 ("x86/sev: Document requirement for linear mapping of guest request buffers")
