CVE-2024-46681

一、漏洞信息
 漏洞编号：[CVE-2024-46681](https://nvd.nist.gov/vuln/detail/CVE-2024-46681)
 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0,6.6.0
 CVSS V3.0分值：
  BaseScore：5.5 Medium
  Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:pktgen: use cpus_read_lock() in pg_net_init()I have seen the WARN_ON(smp_processor_id() != cpu) firingin pktgen_thread_worker() during tests.We must use cpus_read_lock()/cpus_read_unlock()around the for_each_online_cpu(cpu) loop.While we are at it use WARN_ON_ONCE() to avoid a possible syslog flood.
