How to Fix CVE-2026-98045

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-2026-98045, 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: bpf: Mark faultable stack helpers as sleepable The faultable variants of bpf_get_stack() and bpf_get_task_stack() pass may_fault=true into the common stack collection code. Resolving user-space build IDs may then call build_id_parse_file() and block on filesystem reads. Neither helper prototype sets might_sleep. Since prototype selection uses the sleepability of the whole program, the verifier can still allow these helpers from a non-sleepable region within that program, such as an explicit RCU or preemption-disabled region. The task-stack helper can also be called from a non-sleepable timer callback of a sleepable program. Mark both faultable prototypes as sleepable. The existing helper context check then rejects these calls while continuing to allow them in genuinely sleepable contexts.
