An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. A similar issue was previously reported as CVE-2024-47535. This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit. Commit d1fbda62d3a47835d3fb35db8bd42ecc205a5386 contains an updated fix.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-400"],"references":["https://github.com/netty/netty/commit/d1fbda62d3a47835d3fb35db8bd42ecc205a5386","https://github.com/netty/netty/security/advisories/GHSA-389x-839f-4rhx","https://security.netapp.com/advisory/ntap-20250221-0006/","https://github.com/netty/netty/security/advisories/GHSA-389x-839f-4rhx"],"products":["netty:netty"],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-25193","score":0.00391,"percentile":0.33271,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-389x-839f-4rhx","url":"https://osv.dev/vulnerability/GHSA-389x-839f-4rhx","summary":"Denial of Service attack on windows app using Netty","modified":"2026-09-10T03:50:22.454183571Z","packages":[{"ecosystem":"Maven","name":"io.netty:netty-common","purl":"pkg:maven/io.netty/netty-common","ranges":["<4.1.118.Final"],"fixed":["4.1.118.Final"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
