Detailsinfo

A vulnerability, which was classified as critical, was found in Google TensorFlow up to 2.11.0 (Artificial Intelligence Software). Affected is the function nn_ops.fractional_avg_pool_v2/nn_ops.fractional_max_pool_v2. The manipulation with an unknown input leads to a double free vulnerability. CWE is classifying the issue as CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

TensorFlow is an open source machine learning platform. Prior to versions 2.12.0 and 2.11.1, `nn_ops.fractional_avg_pool_v2` and `nn_ops.fractional_max_pool_v2` require the first and fourth elements of their parameter `pooling_ratio` to be equal to 1.0, as pooling on batch and channel dimensions is not supported. A fix is included in TensorFlow 2.12.0 and 2.11.1.

The weakness was published 03/25/2023 as GHSA-f49c-87jh-g47q. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2023-25801 since 02/15/2023. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The current price for an exploit might be approx.
