{"id":"CVE-2026-87825","aliases":["GHSA-947w-pxjj-c7m9"],"url":"https://o3.security/vulnerability/CVE-2026-87825","summary":"zstd-jni 1.3.8-4 through 1.5.7-13 Use-After-Free of Compression and Decompression Dictionaries","details":"zstd-jni before 1.5.7-14 contains a use-after-free vulnerability where streams and contexts hold a dictionary's shared lock only during the load call, allowing the dictionary to be closed while still referenced. Attackers can close a dictionary after associating it with a stream or context, causing subsequent read or write operations to access freed native memory, resulting in silent data corruption or JVM crashes.","published":"2026-09-09T14:32:44.795Z","modified":"2026-09-10T08:13:49.954265Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/luben/zstd-jni/commit/0827ed02551bbd8d6f8e4bbff99d83bf50f91938","label":"luben/zstd-jni@0827ed0"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/87xxx/CVE-2026-87825.json"},{"type":"PACKAGE","url":"https://github.com/luben/zstd-jni"},{"type":"ARTICLE","url":"https://github.com/luben/zstd-jni/blob/v1.5.7-13/src/main/java/com/github/luben/zstd/BaseZstdBufferDecompressingStreamNoFinalizer.java"},{"type":"ARTICLE","url":"https://github.com/luben/zstd-jni/blob/v1.5.7-13/src/main/java/com/github/luben/zstd/ZstdInputStreamNoFinalizer.java"},{"type":"FIX","url":"https://github.com/luben/zstd-jni/commit/0827ed02551bbd8d6f8e4bbff99d83bf50f91938"},{"type":"FIX","url":"https://github.com/luben/zstd-jni/commit/393d7311766abbc285b149302c0fe1f94b16d555"},{"type":"FIX","url":"https://github.com/luben/zstd-jni/commit/a560131d7834598afd9cea6b7c107bc88e915936"},{"type":"ADVISORY","url":"https://github.com/luben/zstd-jni/releases/tag/v1.5.7-14"},{"type":"ADVISORY","url":"https://github.com/luben/zstd-jni/security/advisories/GHSA-947w-pxjj-c7m9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-87825"},{"type":"WEB","url":"https://repo1.maven.org/maven2/com/github/luben/zstd-jni/"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/zstd-jni-1.3.8-4-through-1.5.7-13-use-after-free-of-compression-and-decompression-dictionaries"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T08:13:49.954265Z"}}
