CVE-2026-44630: CWE-789 Memory Allocation with Excessive Size Value in Apache Software Foundation Apache IoTDB
A vulnerability in Apache IoTDB's RPC service allows remote unauthenticated attackers to cause a denial of service by sending a malformed Thrift frame that triggers excessive memory allocation and crashes the system. This affects versions before 1.3.8 and from 2.0.0 before 2.0.9. The issue is fixed in version 2.0.10.
AI Analysis
Technical Summary
CVE-2026-44630 is a memory allocation vulnerability in Apache IoTDB's RPC service caused by improper validation of length fields in Thrift frames. An attacker can send a crafted malformed frame that forces IoTDB to allocate an excessive amount of memory, leading to an OutOfMemoryError and denial of service. This affects Apache IoTDB versions before 1.3.8 and from 2.0.0 up to but not including 2.0.9. The vendor recommends upgrading to version 2.0.10 to address the issue.
Potential Impact
Successful exploitation results in a denial of service condition due to excessive memory allocation and subsequent crash of the IoTDB service. The attacker does not require authentication and can trigger this remotely, potentially disrupting availability of the affected service.
Mitigation Recommendations
Users should upgrade Apache IoTDB to version 2.0.10 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor's recommendation to upgrade.
