How to Fix CVE-2026-90293

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-2026-90293, 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: IB/isert: post the full-feature receive buffers after session registration isert_put_login_tx() posts the full-feature receive buffers before __transport_register_session() runs, so an initiator that does not wait for the final Login Response can still have a SCSI command executed against an se_session whose se_tpg is NULL - the same oops as the previous patch, at target_submit+0xbe. Post them from isert_get_rx_pdu(), which the previous patch already uses to send that response, and post them before that send: the receive queue is filled at the moment the initiator is told it may use it. Allocating there keeps the existing property that a memory allocation failure cannot happen once the final Login Response is on the wire. The receive queue is already empty between the final Login Request and isert_post_recvm(); this moves the second point later, from a median of 92 us to 172 us over 1200 logins. Only an initiator that sends before it has been told to can reach that window, and on IB and RoCE its send is retried there until the buffers appear - isert_rdma_accept() asks for rnr_retry_count = 7. iWARP has no RNR flow control, so there the same send terminates the connection instead. Measured over rxe, 400 login cycles per run, with an initiator that does not wait: an instrumented build counted no entries to isert_recv_done() before the buffers are posted in 10 runs, where that initiator oopsed 8 of 10 unpatched runs and 5 of 10 with only the previous patch. Not tested: iWARP, discovery sessions over iSER, and real HCAs.
