How to Fix CVE-2026-89842

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-2026-89842, 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: Skip NVMe LS reject IOCB when FW not started qla_nvme_xmt_ls_rsp() bails out to the out: label when firmware is not started (!ha->flags.fw_started), but the out: path unconditionally calls qla_nvme_ls_reject_iocb(), which ends in qla2x00_start_iocbs() and an unconditional doorbell write to the request queue in-pointer register. This rings the firmware doorbell and queues an IOCB that stopped or resetting firmware cannot consume, and touches MMIO during the reset/EEH window where fw_started is also clear. Only emit the LS reject IOCB (and ring the doorbell) when fw_started is set; otherwise just clean up and return. The post-allocation failure cases (SRB alloc / qla2x00_start_sp() failure) run with firmware started and still send the reject. Apply the same guard to the reject emission in qla2xxx_process_purls_pkt().
