Subject: [PATCH] UefiPayloadPkg/UefiPayloadEntry: Fix memory corruption
UefiPayloadEntry's AllocatePool() applies the "sizeof" operator to HOB index
rather than the HOB header structure. This yields 4 Bytes compared to the 8
Bytes the structure header requires. Fix the call to allocate the required
space instead.
