The impacted element is the function khaiii::nn::Linear::open of the file src/main/cpp/khaiii/nn/Linear.cpp of the component JSON Config File Handler. The manipulation of the argument hidden_dim/class_num results in out-of-bounds read. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The vendor explains: \"khaiii treats the resource directory (--rsc-dir) as trusted input, like a binary or a shared library. To use this defect, an attacker must already be able to write to that directory. With that access, an attacker can change the analysis results without this defect.\" This vulnerability only affects products that are no longer supported by the maintainer.","published":"2026-10-23T22:16:58.000Z","lastModified":"2026-10-26T13:41:11.000Z","status":"Deferred","sourceIdentifier":"cna@vuldb.com","cvss":{"version":"4.0","score":1.9,"severity":"LOW","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-119","CWE-125"],"affected":[],"epss":{"score":0.00113,"percentile":0.01394,"date":"2026-10-26","history":[{"date":"2026-10-24","score":0.00159,"percentile":0.04629}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.11%).
