CVE-2023-25664Public exploitNetwork attack vector

Process crash via unchecked pooling dimensions

Published Mar 24, 2023 · Updated Feb 19, 2025

Heap buffer overflow in TensorFlow TAvgPoolGrad before 2.11.1 allows remote attackers to crash a process via malformed pooling parameters. AvgPoolingGradOp begins its sharded gradient computation without validating that each output row and column maps to a valid broadcast region. Triggering the CPU operation with incompatible input dimensions and strides causes an out-of-bounds heap access, limiting the grounded impact to process availability.
