How to Fix CVE-2026-93094

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-2026-93094, 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: wifi: ath12k: fix dp_link_peer dangling references on AP vdev rollback ath12k_mac_vdev_create() for an AP vdev creates the bss self-peer via ath12k_peer_create(), which finishes by calling ath12k_dp_link_peer_assign() to publish the dp_link_peer in the dp_hw->dp_peers[peerid_index] RCU table, in the dp_peer's link_peers[] array, and in the per-addr rhashtable. If a step after ath12k_peer_create() fails the function jumps to err_peer_del, which open-codes a WMI peer_delete and waits for the unmap / delete_resp events. The wait_for_peer_delete_done() path relies on ath12k_dp_link_peer_unmap_event() freeing the dp_link_peer when the unmap arrives, but err_peer_del never calls ath12k_dp_link_peer_unassign() first. The published references in the dp_hw RCU table, dp_peer->link_peers[] and the rhashtable are left pointing at the dp_link_peer that unmap_event then frees, producing dangling pointers and use-after-free on subsequent lookups. Replace the open-coded sequence with a call to ath12k_peer_delete(), which already does ath12k_dp_link_peer_unassign() before sending the WMI command. This drops the published references before the dp_link_peer is freed, in the same order as the normal teardown path in ath12k_mac_remove_link_interface(). Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
