{"id":"CVE-2026-88357","published":"2026-09-24T16:17:12.957","lastModified":"2026-09-24T21:08:55.030","description":"nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-1335"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ntop/nDPI/issues/3213","tags":[]},{"url":"https://github.com/ntop/nDPI/pull/3231","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/6698f14bf6025394a537fe23f413cf79e9d13594","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/694231bb43ff21f452fbc2b53fcf6cdc9a99f75f","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/6ce1280c52ed52a97332c3fe58fd2b47b867ec6e","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/8fc3b439920021a77165f8aee4f81b25bc88629e","tags":[]},{"url":"https://github.com/ntop/nDPI/issues/3213","tags":[]}],"exploitRefs":[{"url":"https://github.com/ntop/nDPI/issues/3213","tags":[]},{"url":"https://github.com/ntop/nDPI/pull/3231","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/6698f14bf6025394a537fe23f413cf79e9d13594","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/694231bb43ff21f452fbc2b53fcf6cdc9a99f75f","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/6ce1280c52ed52a97332c3fe58fd2b47b867ec6e","tags":[]},{"url":"https://github.com/utoni/nDPI/commit/8fc3b439920021a77165f8aee4f81b25bc88629e","tags":[]},{"url":"https://github.com/ntop/nDPI/issues/3213","tags":[]}],"hasPoc":true,"ai":null}
