CVE-2026-44060: Network Length Underflow

Subtracting an offset from a network-provided length without prior bounds checking can cause an integer underflow. If the length provided by an attacker is smaller than the offset, the result can wrap around to a large positive integer, resulting in out-of-bounds reads or writes.
