CVE-2026-44978: Stream Padding Underflow
Missing validation of padding length before subtracting from stream end pointer. This can lead to a pointer underflow and subsequent negative length calculation, resulting in a heap out-of-bounds read. Ensure that the padding is checked against the available buffer span before it is subtracted from the end pointer.
