CVE-2026-14683: Uncontrolled Memory Allocation in HdrHistogram
CVE-2026-14683 is a medium severity vulnerability in HdrHistogram versions 2.2.0, 2.2.1, and 2.2.2. It involves uncontrolled memory allocation in the function decodeFromCompressedByteBuffer due to manipulation of the lengthOfCompressedContents argument. Exploitation requires local access. No official patch or remediation has been announced yet.
AI Analysis
Technical Summary
This vulnerability affects the HdrHistogram library up to version 2.2.2 in the method org.HdrHistogram.AbstractHistogram.decodeFromCompressedByteBuffer. An attacker with local access can manipulate the lengthOfCompressedContents parameter to cause uncontrolled memory allocation, potentially leading to resource exhaustion or denial of service. The issue was reported early to the project, but no response or fix has been provided. The CVSS 4.8 score reflects a medium severity with local attack vector and low privileges required.
Potential Impact
The vulnerability allows a local attacker to cause uncontrolled memory allocation by manipulating input to the decodeFromCompressedByteBuffer function. This can lead to resource exhaustion on the affected system, potentially causing denial of service or application instability. There is no indication of remote exploitation or privilege escalation from the available data.
Mitigation Recommendations
No official patch or remediation is currently available. Users should monitor the vendor or project for updates and consider restricting local access to trusted users only to reduce risk. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
