How to Fix CVE-2026-89852

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-2026-89852, 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: Zero mailbox struct in qla2x00_get_firmware_state() The mbx_cmd_t is allocated on the stack but left uninitialized. qla2x00_mailbox_command() has several early-return paths (PCI permanent failure, device failed, EEH busy, ISP abort pending, mailbox access timeout, purge mbox) that return without writing the input mailbox registers back into mcp->mb[]. qla2x00_get_firmware_state() then unconditionally copies mcp->mb[1..6] (and mb[12]) into the caller's states[] array regardless of the return value. On such a failure the copied values are uninitialized kernel stack memory, which is then exposed to userspace via the fw_state and mpi_fw_state sysfs handlers. Zero the mailbox struct so a failed query yields deterministic zeroed state instead of leaking stack contents.
