CVE-2026-0897— Denial of Service in Keras via Excessive Memory Allocation in HDF5 Metadata

Quick assessment

Affected
Google Keras
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Keras是Keras开源的一个多后端深度学习框架。 Keras 3.0.0版本至3.13.0版本存在安全漏洞，该漏洞源于HDF5权重加载组件在分配资源时无限制或节流，可能导致远程攻击者通过特制的.keras归档文件造成内存耗尽和Python解释器崩溃。

Vulnerability Title
Denial of Service in Keras via Excessive Memory Allocation in HDF5 Metadata
Source: CVE Program / CVE List V5
Vulnerability Description
Allocation of Resources Without Limits or Throttling in the HDF5 weight loading component in Google Keras 3.0.0 through 3.13.0 on all platforms allows a remote attacker to cause a Denial of Service (DoS) through memory exhaustion and a crash of the Python interpreter via a crafted .keras archive containing a valid model.weights.h5 file whose dataset declares an extremely large shape.
