How to Fix CVE-2026-80918

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-2026-80918, 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: core: fix number/pointer type confusion on long items When fetch_item() is called by hid_scan_report() on an item with HID_ITEM_TAG_LONG, it stores a pointer to the item data in item->data.longdata instead of storing a value directly in item->data.{u8/u16/u32}. When item_udata() or item_sdata() encounters such an item, it incorrectly assumes that the item is in short format, and therefore returns the lower part of a kernel pointer reinterpreted as a number. When a HID device is connected whose descriptor contains a HID_GLOBAL_ITEM_TAG_REPORT_SIZE encoded in long format with size=4, this causes the lower half of a kernel pointer to be printed into dmesg as a number, like this: hid (null): invalid report_size 107953555 To fix it, let item_udata() and item_sdata() verify that the item is in short format. Note that this bug only affects hid_scan_report(), while the main parsing pass hid_parse_collections() will always bail out when encountering a long item. Sidenote: There are currently no users of data.longdata; maybe we should just remove any parsing of long-format descriptors as a follow-up.
