lz4-java: yawkat LZ4 Java provides LZ4 compression for Java
CVE-2026-59949 is fixed in lz4-java on 1 platform by DEBIAN-CVE-2026-59949 (version 1.11.2+ds1-1), released September 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
