Subject: [PATCH] UefiPayloadPkg/UefiPayloadEntry: Fix memory corruption
Date: Sun, 8 Aug 2021 19:39:53 +0000 [thread overview]
Message-ID: <efa510e3eb820b31f16ac6b79db183d7ad235080.1628365054.git.mhaeuser@posteo.de> (raw)
In-Reply-To: <5df11a13422732b9c03c120775a2b4dd0a49182f.1628444003.git.mhaeuser@posteo.de>
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.
