[Bug 1896288] [NEW] Event hash and digest mismatch for event logged by shim - Binary BIOS Measurements

[VINAY RAJESH]

Public bug reported:

In the binary bios measurements, the hash of the event measured by shim
does not match the event digest in the measurements. This is due to an
extra zero byte in the event that is not accounted for in the data that
is measured to the PCR.
