CVE-2022-41974

一、漏洞信息
 漏洞编号：[CVE-2022-41974](https://nvd.nist.gov/vuln/detail/CVE-2022-41974)
 漏洞归属组件：[multipath-tools](https://gitee.com/src-openeuler/multipath-tools)
 漏洞归属的版本：0.8.4,0.8.5,0.8.7
 CVSS V3.0分值：
  BaseScore：7.8 High
  Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
 漏洞简述：
  multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.
