CVE-2026-104016 jackson-dataformat-protobuf: signed integer overflow in string-length paths allows unbounded array allocation and OutOfMemoryError

ProtobufParser parses length-prefixed protobuf string and bytes fields by checking inputPtr + len = inputEnd and then, on the fast path, calling finishShortTextlen. Both use 32-bit signed integer arithmetic. When an attacker supplies a varint decoding to a length near Integer.MAXVALUE, inputPtr +...
