Please can somebody help with this issue?
A/ Product: VMware Fusion Player 13.0.2 (21581413)
B/ Guest OS : ubuntu-22.04.2-live-server-arm64
C/ Configuration of the Guest OS virtual machine : TPM enabled
D/ Issue : the TPM event log is incorrect for PCR #0 (for other PCR registers it is correct).
How to reproduce the issue :
1. Install Ubuntu tpm2-tools package
sudo apt-get install tpm2-tools
2. Read the value of PCR #0 (sha256) directly from the TPM:
sudo tpm2_pcrread sha256:0
=> returned value for PCR #0 (sha256):
0 : 0x785648C6609882151E53EBA170CED62E6D3DA80D4EEE909493374F6846A8CD25
3. Compute the value of PCR #0 (sha256) from the TPM event log:
sudo tpm2_eventlog /sys/kernel/security/tpm0/binary_bios_measurements
=> returned value for PCR #0 (sha256):
0 : 0x4666fea59753142fbd5598fd41fe0f09a6ad3dd76ba498795576a5afba74a8a4
4. The two returned values differ. (For the other PCR registers, the values match).
E/ Why issue is a problem: it is impossible to use Linux Integrity Measurement Architecture (IMA) on the guest OS.
F/ Additional information
The issue also occurs with guest ubuntu-23.04-live-server-arm64
The issue does not occur on different virtualization infrastructure that support TPM, such as GCP shielded VM.
