Title: Google TensorFlow BaseCandidateSamplerOp缓冲区错误漏洞

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 2.8.4之前版本、2.9.0及其之后，2.9.3之前版本存在缓冲区错误漏洞，该漏洞源于“BaseCandidateSamplerOp”函数对用户提供的数据缺乏验证，“true_classes”中的值大于“range_max”时，攻击者可利用漏洞导致堆外读取。

Severity: 高

Patch Name: Google TensorFlow BaseCandidateSamplerOp缓冲区错误漏洞的补丁

Patch 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 2.8.4之前版本、2.9.0及其之后，2.9.3之前版本存在缓冲区错误漏洞，该漏洞源于“BaseCandidateSamplerOp”函数对用户提供的数据缺乏验证，“true_classes”中的值大于“range_max”时，攻击者可利用漏洞导致堆外读取。目前，供应商发布了安全公告及相关补丁信息，修复了此漏洞。

CVE-2022-41880 (GCVE-0-2022-41880)

Vulnerability from cvelistv5

Published

2022-11-18 00:00

Modified

2025-04-22 16:07

Severity ?

6.8 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:H

CWE

CWE-125 - Out-of-bounds Read

Summary

TensorFlow is an open source platform for machine learning. When the `BaseCandidateSamplerOp` function receives a value in `true_classes` larger than `range_max`, a heap oob read occurs. We have patched the issue in GitHub commit b389f5c944cadfdfe599b3f1e4026e036f30d2d4. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
