Advisory Summary

CVE-2026-102716 is a HIGH security vulnerability vulnerability (CWE-401: Missing Release of Memory after Effective Lifetime) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-102716

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-102716, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-401: Missing Release of Memory after Effective Lifetime, where the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An unauthenticated client can drain the RTSP server's packet pool with a couple of dozen requests that carry a Session header the parser cannot convert. The Session branch returns the raw NetX error code instead of an RTSP status code: ```c /* addons/rtsp/nx_rtsp_server.c:2754 */ status = _nx_utility_string_to_uint(field_value_ptr, field_value_length, &session_id); if (status) { return(status); /* NX_INVALID_PARAMETERS / NX_SIZE_ERROR / NX_OVERFLOW */ } ``` Every other branch of the same function maps its failure to an RTSP status first. The CSeq branch eighteen lines earlier does exactly that (line 2736 returns NX_RTSP_STATUS_CODE_BAD_REQUEST). The raw code then reaches `_nx_rtsp_server_error_response_send` (nx_rtsp_server.c:1234), which does not recognise it, takes a path that returns without releasing the response packet it already allocated, and the block never goes back to the pool. Six requests with an empty Session header against a 22 packet pool: ``` valid requests: after request 6: pool available = 21, AFTER = 22 / 22 malformed requests: after request 6: pool available = 16, AFTER = 17 / 22 ``` One block per request, not returned when the client disconnects. Twenty six requests take the pool to zero and the server starts failing allocations, after which it serves nobody. If the pool is shared with the rest of the application, as it is in the shipped sample, the rest of the stack stops with it. Convert the `_nx_utility_string_to_uint` failure in the Session branch into NX_RTSP_STATUS_CODE_BAD_REQUEST the way the CSeq branch does, and release the response packet on every exit path of `_nx_rtsp_server_error_response_send`.
