Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-68389

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-2026-68389, 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 General Security Weakness. 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: Bluetooth: hci_qca: Clear memdump state on invalid dump size qca_controller_memdump() allocates qca->qca_memdump before processing the first dump packet. For a sequence-zero packet it then disables IBS, marks memdump collection active, and reads the advertised dump size. If the controller reports a zero dump size, the error path frees the local qca_memdump object and returns without clearing qca->qca_memdump or undoing the collection state. A later memdump work item initializes its local pointer from qca->qca_memdump and skips allocation when that pointer is non-NULL, so it can operate on freed memory. The stale collection and IBS-disabled flags can also leave waiters or later transmit handling blocked behind an aborted dump. Clear the saved pointer and memdump state before returning from the invalid-size path, matching the cleanup used when hci_devcd_init() fails. A static analysis checker reported the stale memdump state, and manual source review confirmed the invalid-size failure path.
