A truncated firmware image\ncan make the parser read beyond the copied firmware buffer. A value\nsmaller than the four-byte count field also underflows, producing a very\nlarge length.\n\nRead the little-endian field with get_unaligned_le32(), as previously\nproposed by David Lechner. Validate the header size, reject an\nunderflowed length, ensure the resulting payload is contained in the\nfirmware image, and require it to contain whole register/value entries."
