How to Fix CVE-2026-98292

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-2026-98292, 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: Bluetooth: btmtksdio, btmtkuart: validate WMT event length before struct access btmtksdio.c and btmtkuart.c cast a received WMT event straight to struct btmtk_hci_wmt_evt and read its op/flag fields without checking the event is long enough to contain them, unlike btmtk.c. The FUNC_CTRL case then further casts to struct btmtk_hci_wmt_evt_funcc and reads its 2-byte status field, again without a length check. Firmware that sends a short or malformed WMT event makes both drivers read past the end of the received SKB. Mirror btmtk.c: validate the base WMT header with skb_pull_data() before touching any of its fields, and when a FUNC_CTRL event turns out to be the short, header-only form (a plain enable/disable ack with no status word), decode the result from the header's own flag byte instead (0 = success, otherwise failure). Verified setup on MT7920, MT7921, MT7922 and MT7925: no regression.
