{"id":"CVE-2026-116590","aliases":["GHSA-xqrx-qh46-34m7"],"url":"https://o3.security/vulnerability/CVE-2026-116590","summary":"snappy-java: JVM crash from unchecked ranges in Snappy.arrayCopy and SnappyOutputStream.rawWrite","details":"### Impact\n`Snappy.arrayCopy(Object src, int offset, int byteLength, Object dest, int destOffset)` called a native `memcpy` without validating the ranges. A negative or oversized `byteLength` or offset read or wrote outside the arrays and crashed the JVM. `SnappyOutputStream.rawWrite` and `SnappyInputStream.rawRead`, and therefore the typed-array `write`/`read` methods, pass caller-supplied ranges to this method.\n\n### Patches\nFixed in 1.1.10.9 (#741). `Snappy.arrayCopy` checks both ranges before copying. The stream `read`/`write` methods validate offsets and lengths, and reject typed-array ranges whose byte size overflows `int`.\n\n### Workarounds\nValidate offsets and lengths before calling these methods.","published":"2026-10-26T21:48:15.468Z","modified":"2026-10-29T02:48:28.769102989Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Maven","name":"org.xerial.snappy:snappy-java","fixedVersion":"1.1.10.9"}],"fix":{"url":"https://github.com/xerial/snappy-java/commit/2d7ca71c087a98f1219fb2d51909f3891c3ce77b","label":"xerial/snappy-java@2d7ca71"},"references":[{"type":"WEB","url":"https://github.com/xerial/snappy-java/releases/tag/v1.1.10.9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/116xxx/CVE-2026-116590.json"},{"type":"ADVISORY","url":"https://github.com/xerial/snappy-java/security/advisories/GHSA-xqrx-qh46-34m7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-116590"},{"type":"FIX","url":"https://github.com/xerial/snappy-java/commit/2d7ca71c087a98f1219fb2d51909f3891c3ce77b"},{"type":"FIX","url":"https://github.com/xerial/snappy-java/pull/741"},{"type":"PACKAGE","url":"https://github.com/xerial/snappy-java"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-29T02:48:28.769102989Z"}}
