一、漏洞信息
漏洞编号:CVE-2024-2496
漏洞归属组件:libvirt
漏洞归属的版本:6.2.0
CVSS V3.0分值:
BaseScore:5.0 Medium
Vector:CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H
漏洞简述:
A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This issue can occur when detaching a host interface while at the same time collecting the list of interfaces via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by causing the libvirt daemon to crash.
