Title

Google TensorFlow资源管理错误漏洞（CNVD-2021-92552）

Description

Google TensorFlow是美国谷歌（Google）公司的一套用于机器学习的端到端开源平台。 Google TensorFlow 存在资源管理错误漏洞，该漏洞源于 CollectiveReduceV2 的异步实现存在内存泄漏和释放后使用问题。发生这种情况是由于异步计算以及仍然访问了来自 `std：：move()` 的对象这一事实。目前没有详细的漏洞细节提供。

CVE-2021-41220 (GCVE-0-2021-41220)

Vulnerability from cvelistv5 – Published: 2021-11-05 22:20 – Updated: 2024-08-04 03:08

Title

Use after free in `CollectiveReduceV2`

Summary

TensorFlow is an open source platform for machine learning. In affected versions the async implementation of `CollectiveReduceV2` suffers from a memory leak and a use after free. This occurs due to the asynchronous computation and the fact that objects that have been `std::move()`d from are still accessed. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, as this version is the only one that is also affected.

Severity

7.8 (High)
