How to Fix CVE-2026-46248

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-2026-46248, 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: clear stale link mapping of ahvif->links_map When an arvif is initialized in non-AP STA mode but MLO connection preparation fails before the arvif is created (arvif->is_created remains false), the error path attempts to delete all links. However, link deletion only executes when arvif->is_created is true. As a result, ahvif retains a stale entry of arvif that is initialized but not created. When a new arvif is initialized with the same link id, this stale mapping triggers the following WARN_ON. WARNING: drivers/net/wireless/ath/ath12k/mac.c:4271 at ath12k_mac_op_change_vif_links+0x140/0x180 [ath12k], CPU#3: wpa_supplicant/275 Call trace: ath12k_mac_op_change_vif_links+0x140/0x180 [ath12k] (P) drv_change_vif_links+0xbc/0x1a4 [mac80211] ieee80211_vif_update_links+0x54c/0x6a0 [mac80211] ieee80211_vif_set_links+0x40/0x70 [mac80211] ieee80211_prep_connection+0x84/0x450 [mac80211] ieee80211_mgd_auth+0x200/0x480 [mac80211] ieee80211_auth+0x14/0x20 [mac80211] cfg80211_mlme_auth+0x90/0xf0 [cfg80211] nl80211_authenticate+0x32c/0x380 [cfg80211] genl_family_rcv_msg_doit+0xc8/0x134 Fix this issue by unassigning the link vif and clearing ahvif->links_map if arvif is only initialized but not created.
