CVE-2026-64273: Software Security Vulnerability Vulnerability
HIGHCVE-2026-64273 is a HIGH (CVSS 7.8) security vulnerability vulnerability (CWE-129: Improper Validation of Array Index) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-64273 at a Glance
Security Impact
CVSS: 7.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-64273
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.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-64273, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze 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 CWE-129: Improper Validation of Array Index, where the product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. 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.

"details" : "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: iforce - bound the device-reported force-feedback effect index\n\niforce_process_packet() handles a status report (packet id 0x02) by\ntaking a force-feedback effect index straight from the device wire and\nusing it to address the per-effect state array:\n\n\ti = data[1] & 0x7f;\n\tif (data[1] & 0x80) {\n\t\tif (!test_and_set_bit(FF_CORE_IS_PLAYED,\n\t\t\t\t iforce->core_effects[i].flags))\n\t\t\t...\n\t} else if (test_and_clear_bit(FF_CORE_IS_PLAYED,\n\t\t\t\t iforce->core_effects[i].flags)) {\n\t\t...\n\t}\n\nThe index is masked only with 0x7f, so it ranges 0..127, but\ncore_effects[] holds only IFORCE_EFFECTS_MAX (32) entries. For an index\nof 32..127 the test_and_set_bit()/test_and_clear_bit() is an\nout-of-bounds single-bit read-modify-write past the array. core_effects[]\nis the second-to-last member of struct iforce, so the write lands in the\ntrailing members and beyond the embedding kzalloc()'d iforce_serio /\niforce_usb object.\n\ndata[1] is unvalidated device payload on both transports (the USB\ninterrupt endpoint and serio), and the status path is not gated on force\nfeedback being present, so a malicious or counterfeit device can set or\nclear a bit at an attacker-chosen offset past the object.\n\nReject an out-of-range index instead of indexing with it. Bound against\nthe array dimension IFORCE_EFFECTS_MAX rather than dev->ff->max_effects so\nthe check guarantees memory safety regardless of how many effects the\ndevice registered. A legitimate \"effect started/stopped\" status always\ncarries an index below IFORCE_EFFECTS_MAX, so well-formed devices are\nunaffected; the neighbouring mark_core_as_ready() loop is already bounded\nand is left untouched.",
