This includes:

  • Enforce TPM response HMAC length checks
  • Validate GetProductInfo payload length

@LinuxJedi
Enforce TPM response HMAC length checks
ae73063 
Reject zero-length or mismatched response HMACs for authenticated sessions so forged SWTPM replies fail verification.
@LinuxJedi
Validate GetProductInfo payload length
4f6282b 
Reject undersized SWTPM responses before copying product info to avoid signed underflow and out-of-bounds access.
