Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through repeated allocation of large buffers in the LZ4FrameInputStream.readHeader process. An attacker can cause excessive CPU and garbage collection usage by providing specially...

Overview org.lz4:lz4-java is a Java port of the LZ4 compression algorithm and the xxHash hashing algorithm. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through repeated allocation of large buffers in the LZ4FrameInputStream.readHeader...

CVE-2026-106450

yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.4, net.jpountz.lz4.LZ4FrameInputStream readHeader allocates two new 4 MiB block buffers whenever a maximum-block-size frame header is read, and the default concatenated-frame mode allows attacker-controlled streams containing many...
