How to Fix CVE-2026-80768

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-2026-80768, 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: HID: ft260: fix stack-use-after-return write in I2C read race ft260_i2c_read() points dev->read_buf at a caller-supplied buffer (often an on-stack variable), arms a completion and waits up to five seconds for the device to return the data. The HID input callback ft260_raw_event() runs in the input/IRQ path, independent of the dev->lock mutex held by the read path, and copies the device-supplied payload into dev->read_buf after a plain NULL check. These two paths share read_buf, read_idx and read_len with no serialization. If the device delays its response until the read times out, ft260_i2c_read() resets the controller, clears read_buf and returns, unwinding the stack frame the buffer lived in. A response that arrives at that moment lets ft260_raw_event() pass the NULL check and then memcpy() the device-controlled payload into the now-freed stack location, a bounded but attacker-influenced stack-use-after-return write triggerable by malicious or malfunctioning hardware. Add a dedicated spinlock that serializes every access to read_buf, read_idx and read_len. ft260_raw_event() now holds it across the NULL check, the memcpy and the index update, while the read path takes it when arming and when clearing the buffer, so the teardown can no longer slip between the check and the copy.
