How to Fix CVE-2026-80651

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-2026-80651, 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: crypto: ccp/sev-dev-tsm - bail out early when pdev->bus is NULL dsm_create() initially checks pdev->bus when computing segment_id: u8 segment_id = pdev->bus ? pci_domain_nr(pdev->bus) : 0; But the next two lines unconditionally dereference pdev->bus via pcie_find_root_port() and especially pci_dev_id(pdev), which expands to PCI_DEVID(dev->bus->number, dev->devfn). If pdev->bus is in fact NULL, segment_id is initialised to 0 but the very next statement crashes the kernel. smatch flags this: drivers/crypto/ccp/sev-dev-tsm.c:253 dsm_create() error: we previously assumed 'pdev->bus' could be null (see line 251) Make the NULL handling consistent: if pdev->bus is NULL the device has no PCI context to work with and SEV TIO setup cannot proceed, so return -ENODEV before any of the bus-dependent lookups. The remaining initialisation now runs only on the path where pdev->bus is known to be valid. No change for callers where pdev->bus is non-NULL, which is the only case where dsm_create() did meaningful work before this change.
