Title: QEMU资源管理错误漏洞（CNVD-2024-14789）

Description:

QEMU是法国法布里斯-贝拉（Fabrice Bellard）个人开发者的一套模拟处理器软件。该软件具有速度快、跨平台等特点。

QEMU中的NVM Express控制器 (NVME) 仿真中存在安全漏洞，该漏洞源于当可重入写入触发重置函数 nvme_ctrl_reset() 时，数据结构将被释放，从而导致释放后使用问题。攻击者可以利用该漏洞使主机上的QEMU 进程崩溃，从而导致拒绝服务条件，或者可能在主机上的QEMU进程上下文中执行任意代码。

CWE

CWE-416 - - Use After Free

Summary

A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.
