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

How to Fix CVE-2026-89849

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-2026-89849, 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: Reject non-SCSI SRB on status IOCB fast path qla2x00_status_entry() filters out non-TYPE_SRB entries and the SRB_NVME_CMD, SRB_BIDI_CMD and SRB_TM_CMD types, then falls through to a SCSI fast path that assumes the command is an SRB_SCSI_CMD. The first thing on that path, qla_chk_edif_rx_sa_delete_pending(), and the subsequent handling both evaluate GET_CMD_SP(sp), i.e. sp->u.scmd.cmd. The srb u union overlays the SCSI command pointer with other command layouts (bsg_job, iocb_cmd). If firmware delivers an unexpected STATUS_TYPE IOCB for a non-SCSI handle, sp->u.scmd.cmd can read as a non-NULL garbage pointer, bypassing the NULL checks in qla_chk_edif_rx_sa_delete_pending() and at the cp == NULL test, and leading to a wild pointer dereference. Reject any SRB whose type is not SRB_SCSI_CMD before entering the fast path. The outstanding_cmds slot is left untouched so a genuinely non-SCSI command still completes through its proper handler.
