Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-89620

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-2026-89620, 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: intel-thc-hid: intel-quickspi: validate report size before copy write_cmd_to_txdma() builds an output report in qsdev->report_buf, a heap buffer allocated in quickspi_alloc_report_buf() to the device-descriptor derived max_report_len (a few hundred bytes for a touch controller). It copies the caller-supplied report into that buffer: memcpy(write_buf->content, report_buf, report_buf_len); The HID core caps a report at HID_MAX_BUFFER_SIZE (16384) by default, and quickspi_hid_ll_driver does not set max_buffer_size, so the length reaches the driver unbounded. A hidraw SET_REPORT/SET_FEATURE ioctl carrying a report larger than max_report_len therefore overflows report_buf with attacker-controlled length and content. Record the report_buf allocation size and reject reports that do not fit before copying, matching the equivalent guard in the intel-quicki2c sibling (quicki2c_init_write_buf()) and the hid-goodix-spi fix. write_cmd_to_txdma() writes the output report header ahead of the content in the same buffer, so size the allocation to cover the header as well. That keeps the added bound from rejecting a maximum-sized report.
