 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:net_sched: qfq: Fix double list add in class with netem as child qdiscAs described in Gerrard s report [1], there are use cases where a netemchild qdisc will make the parent qdisc s enqueue callback reentrant.In the case of qfq, there won t be a UAF, but the code will add the sameclassifier to the list twice, which will cause memory corruption.This patch checks whether the class was already added to the agg->activelist (cl_is_active) before doing the addition to cater for the reentrantcase.[1] https://lore.kernel.org/netdev/CAHcdcOm+03OD2j6R0=YHKqmy=VgJ8xEOKuP6c7mSgnp-TEJJbw@mail.gmail.com/
