一、漏洞信息
 漏洞编号：[CVE-2024-3447](https://nvd.nist.gov/vuln/detail/CVE-2024-3447)
 漏洞归属组件：[qemu](https://gitee.com/src-openeuler/qemu)
 漏洞归属的版本：4.1.0,5.2.0,6.2.0,7.2.0
 CVSS V2.0分值：
  BaseScore：0.0 Low
  Vector：CVSS：2.0/
 漏洞简述：
  A heap-based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s->data_count` and the size of  `s->fifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.
