How to Fix CVE-2026-89861

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-2026-89861, 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: scsi: qla2xxx: Hold vport reference in qla24xx_report_id_acquisition() In the format 1 path, the virtual port is located on ha->vp_list while holding vport_slock, but the lock is dropped before vp is used: qla_update_host_map() is called and VP_IDX_ACQUIRED/REGISTER_FC4_NEEDED/ REGISTER_FDMI_NEEDED are set on vp. No reference is taken across that window, so a concurrent qla24xx_deallocate_vp_id() can tear the vport down and free it, leading to a use-after-free. Take a vport reference (vref_count) under vport_slock when the matching vp is found, and drop it after the last use of vp. qla24xx_deallocate_vp_id() waits for vref_count to reach zero before unlinking and freeing the vport, so the pointer stays valid. This matches the reference idiom already used by the other ha->vp_list traversals.
