Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Rizin是Rizin组织的一个免费的开源逆向工程框架。用于分析二进制文件、反汇编代码、调试程序、作为取证工具、作为能够打开磁盘文件的可编写脚本的命令行十六进制编辑器等等。 Rizin 存在安全漏洞，该漏洞源于其分析攻击者特别设计的基于HPPA架构的ELF64二进制文件时会释放一个未初始化的（可能是用户控制的，取决于构建）内存地址，从而导致rizin崩溃。
