How to Fix CVE-2026-97955

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-2026-97955, 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: mana: restore the XDP program pointer when pre-allocation fails mana_xdp_set() publishes the new program into apc->bpf_prog before it allocates anything, because mana_pre_alloc_rxbufs() sizes the buffers from it via mana_get_rxbuf_cfg(). When that allocation fails the function returns the error directly, skipping the err_dealloc_rxbuffs label which is the only place that restores the previous pointer. The attach is reported as failed, so the BPF core drops the reference it held for the caller and the program can be freed, while apc->bpf_prog still points at it. The next consumer of mana_xdp_get() - typically mana_chn_setxdp() from mana_alloc_queues() on the following ifup, or after a TX timeout reset - then calls bpf_prog_add() on freed memory. This is reachable from an ordinary "ip link set dev ethX xdp obj ..." whenever the per-queue RX buffer pre-allocation cannot be satisfied. Restore the previous program on that error path.
