{"id":"DEBIAN-CVE-2026-59949","details":"yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.1, JNI-backed XXHash implementations fail to validate the byte array object and the off and len arguments in XXHashFactory.nativeInstance().hash32().hash(), XXHashFactory.nativeInstance().hash64().hash(), XXHashFactory.nativeInstance().newStreamingHash32().update(), and XXHashFactory.nativeInstance().newStreamingHash64().update(), allowing null arrays or oversized ranges to reach native code, read outside the Java array, and fatally terminate the JVM. This issue is fixed in version 1.11.1.","modified":"2026-09-19T22:47:26.812934166Z","published":"2026-08-18T15:16:56.160Z","upstream":["CVE-2026-59949"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-59949"}],"affected":[{"package":{"name":"lz4-java","ecosystem":"Debian:12","purl":"pkg:deb/debian/lz4-java?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.11.2+ds1-1","1.11.2+ds1-2","1.11.2+ds1-3","1.8.0-3","1.8.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59949.json"}},{"package":{"name":"lz4-java","ecosystem":"Debian:13","purl":"pkg:deb/debian/lz4-java?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.11.2+ds1-1","1.11.2+ds1-2","1.11.2+ds1-3","1.8.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59949.json"}},{"package":{"name":"lz4-java","ecosystem":"Debian:14","purl":"pkg:deb/debian/lz4-java?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.11.2+ds1-1"}]}],"versions":["1.8.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59949.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H"}]}
