CVE-2022-2639

一、漏洞信息
 漏洞编号：[CVE-2022-2639](https://nvd.nist.gov/vuln/detail/CVE-2022-2639)
 漏洞归属组件：[openvswitch](https://gitee.com/src-openeuler/openvswitch)
 漏洞归属的版本：2.12.0,2.12.4,2.17.5
 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：
  An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.

二、漏洞分析结构反馈
 影响性分析说明：
      在openvswitch内核模块中发现了一个整数强制错误。在为新流的新操作复制和保留内存时，如果操作数量足够多，则reserve_sfa_size()函数不会按预期返回-EMSGSIZE，从而可能导致越界写入访问。此漏洞允许本地用户崩溃或潜在地提升其在系统上的权限。注:由于master/2403-LTS分支不涉及漏洞代码(https://github.com/openvswitch/ovs/commit/422e90437854c441a0b274d3bf06ce7d6bbf9de0)，即不受影响
