How to Fix CVE-2026-80756

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-2026-80756, 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: selinux: do not cancel a policy conversion that never started sel_write_load() calls selinux_policy_cancel() when sel_make_policy_nodes() fails, and that helper dereferences the outgoing policy to cancel its sidtab conversion. On the first policy load there is no outgoing policy: security_load_policy() returns early for that case, before it converts anything, and state->policy is still NULL. A first load that fails while building the selinuxfs tree therefore takes a NULL dereference in selinux_policy_cancel(), reached from a write(2) to /sys/fs/selinux/load. Skip the cancel when there is no old policy, mirroring the check security_load_policy() already makes before it converts.
