一、漏洞信息
 漏洞编号：[CVE-2021-3409](https://nvd.nist.gov/vuln/detail/CVE-2021-3409)
 漏洞归属组件：[qemu](https://gitee.com/src-openeuler/qemu)
 漏洞归属的版本：4.0.0,4.0.1,4.1.0,5.2.0
 CVSS V3.0分值：
  BaseScore：5.7 Medium
  Vector：CVSS：3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L
 漏洞简述：
  The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.
