      <title>CVE-2026-59949 — yawkat LZ4 Java: JVM Crash via Null Byte Array in lz4-java Streaming XXHash JNI (StreamingXXHash32JNI / StreamingXXHash…</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-59949</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; yawkat lz4-java&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
