CVE-2026-102554— Denial of Service via Eager Array Allocation During Deserialization in Guava

Quick assessment

Affected
Google Guava
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.

在 Google Guava 4.0 至 33.7.1 版本中，Java 对象反序列化过程存在无限制或未进行速率控制的资源分配问题（CWE-770），攻击者可由此导致拒绝服务（DoS）漏洞，表现为抛出 OutOfMemoryError。当反序列化 CompactHashMap、CompactHashSet 或 MapMakerInternalMap 实例时，Guava 会根据调用方指定的大小参数急切地分配数组，且未对此进行速率控制或限制，从而允许通过构造恶意序列化流耗尽内存。

Vulnerability Title
Denial of Service via Eager Array Allocation During Deserialization in Guava
Source: CVE Program / CVE List V5
Vulnerability Description
Allocation of resources without limits or throttling (CWE-770) during Java object deserialization in Google Guava versions 4.0 through 33.7.1 allows an attacker to cause a Denial of Service via OutOfMemoryError. When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams.
