How to Fix CVE-2026-98272

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-2026-98272, 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: net: mvpp2: prevent buffer overflow in page_pool allocation The per‑processor buffering scheme is supported only if the number of pools (nrxqs * 2) does not exceed MVPP2_BM_MAX_POOLS (8). This is already checked in mvpp2_probe() during the initial activation of percpu_pools. However, mvpp2_change_mtu() may later call mvpp2_bm_switch_buffers(priv, true) without this check, which can lead to an out-of-bounds access in the priv->page_pool array in mvpp2_bm_init(). The array is sized to hold MVPP2_PORT_MAX_RXQ entries, and mvpp2_get_nrxqs() may return exactly that value. The per-CPU scheme then doubles it to nrxqs * 2, exceeding the array bounds. Check that the hardware version is MVPP22 or newer and that the number of pools (nrxqs * 2) does not exceed MVPP2_BM_MAX_POOLS before switching to per-CPU mode. Found by Linux Verification Center (linuxtesting.org) with SVACE.
