How to Fix CVE-2026-97531

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-2026-97531, 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 vport under deletion in report ID acquisition qla24xx_report_id_acquisition() format-1 handling walks ha->vp_list under vport_slock, takes a vref_count on the matching vport and calls qla_update_host_map() to register its port id. A vport teardown via qla24xx_vport_delete() sets VPORT_DELETE, then qla24xx_disable_vp() removes the vport from the host_map btree and zeroes vha->d_id (RESET_AL_PA). The vport is only unlinked from vp_list later, in qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX) but does not touch host_map. In the window in between, report ID acquisition can still find the vport on vp_list and call qla_update_host_map(); with d_id already zeroed it takes the btree_insert32() path and re-inserts the dying vport into host_map. Nothing cleans that entry afterwards, so once scsi_host_put() frees the vha a later host_map lookup dereferences freed memory. Skip a vport that has VPORT_DELETE set before taking the reference, so it is neither re-registered nor scheduled for DPC re-registration. This mirrors the existing guard in qla2x00_alert_all_vps().
