Attackers can supply negative offset values that bypass bounds checks and reach the native frame-header parser, causing out-of-bounds memory reads that lead to information disclosure or JVM crashes.","published":"2026-09-10T18:18:16.560","modified":"2026-09-10T18:18:16.560","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/luben/zstd-jni/commit/dd08685ef913a32e76fb27f43470035c06758646","label":"luben/zstd-jni@dd08685"},"references":[{"type":"WEB","url":"https://github.com/luben/zstd-jni"},{"type":"WEB","url":"https://github.com/luben/zstd-jni/blob/v1.5.7-13/src/main/java/com/github/luben/zstd/Zstd.java#L730"},{"type":"WEB","url":"https://github.com/luben/zstd-jni/blob/v1.5.7-13/src/main/native/jni_zstd.c#L87"},{"type":"WEB","url":"https://github.com/luben/zstd-jni/commit/dd08685ef913a32e76fb27f43470035c06758646"},{"type":"WEB","url":"https://github.com/luben/zstd-jni/releases/tag/v1.5.7-14"},{"type":"WEB","url":"https://github.com/luben/zstd-jni/security/advisories/GHSA-rm53-6wf5-f34m"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/zstd-jni-1.5.5-6-through-1.5.7-13-out-of-bounds-read-via-negative-offset"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T18:18:16.560"}}
