CVE-2022-23562Network attack vector

Service interruption via unchecked Range size arithmetic

Published Feb 4, 2022 · Updated Apr 23, 2025

Integer overflow in Google TensorFlow Range before 2.5.3, 2.6.0 through 2.6.2, and 2.7.0 allows remote authenticated users to interrupt services. RangeOp and RangeSize compute the output length from start, limit, and delta, then cast it to int64_t without rejecting values above INT64_MAX. A caller must supply Range operands that overflow the size calculation; the resulting undefined behavior or extreme allocation interrupts the hosting process.
