Key store file assertion error

[CHr15W3]

Hi,
I'm having some trouble analyzing the attached image (the second part of which should be a zen5 UEFI).

When analyzing this, the assertion in key_store_file.py:152, assert self.size == self.buffer_size fails. Dumping these variables, as well as the key_store_size and _start from the calling function yields

key_store_start=256
key_store_size=5744
self.size=4158800887
self.buffer_size=5744

, compared to

key_store_start=256
key_store_size=10144
self.size=10144
self.buffer_size=10144

for a previously, correctly parsed entry.

Unfortunately, I don't know the format very well, but could this be a misidentified entry and therefore result in the header being parsed the wrong way?

Thanks and best!

Hi Chris, have you tried the work-in-progress Zen 5 branch?
