How to Fix CVE-2026-80870

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-2026-80870, 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: drm/amdkfd: Validate CRIU-restored IDs before idr_alloc The KFD CRIU restore flow restores previously saved object IDs from userspace. For event restore: kfd_criu_restore_event() -> create_signal_event() / create_other_event() -> allocate_event_notification_slot() -> idr_alloc(..., *restore_id, *restore_id + 1, ...) For BO restore: criu_restore_memory_of_gpu() -> idr_alloc(..., bo_priv->idr_handle, ...) In both cases, the restored ID comes from userspace-provided CRIU data. idr_alloc() expects the ID range values to fit within signed int limits. If a restored ID is larger than INT_MAX, it can trigger a WARN in the IDR layer. A kernel WARN is undesirable because it prints a warning trace and may cause a panic or reboot on systems with panic_on_warn enabled. Smatch reported these paths as allowing unchecked userspace values to reach idr_alloc(). Add INT_MAX validation before using restored IDs in: - kfd_criu_restore_event() - criu_restore_memory_of_gpu() If the restored ID is invalid, return -EINVAL. This prevents invalid restore data from reaching the IDR layer and avoids WARN-triggering paths, while keeping valid restore behavior unchanged.
