Advisory Summary

CVE-2026-43180 is a HIGH (CVSS 7.8) security vulnerability vulnerability (CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-43180

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-2026-43180, 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-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. 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

In the Linux kernel, the following vulnerability has been resolved: net: usb: kaweth: remove TX queue manipulation in kaweth_set_rx_mode kaweth_set_rx_mode(), the ndo_set_rx_mode callback, calls netif_stop_queue() and netif_wake_queue(). These are TX queue flow control functions unrelated to RX multicast configuration. The premature netif_wake_queue() can re-enable TX while tx_urb is still in-flight, leading to a double usb_submit_urb() on the same URB: kaweth_start_xmit() { netif_stop_queue(); usb_submit_urb(kaweth->tx_urb); } kaweth_set_rx_mode() { netif_stop_queue(); netif_wake_queue(); // wakes TX queue before URB is done } kaweth_start_xmit() { netif_stop_queue(); usb_submit_urb(kaweth->tx_urb); // URB submitted while active } This triggers the WARN in usb_submit_urb(): "URB submitted while active" This is a similar class of bug fixed in rtl8150 by - commit 958baf5eaee3 ("net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast"). Also kaweth_set_rx_mode() is already functionally broken, the real set_rx_mode action is performed by kaweth_async_set_rx_mode(), which in turn is not a no-op only at ndo_open() time.
