Vulnerability Data

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…

Why these techniques?

The NULL pointer dereference in libvirt's udevConnectListAllInterfaces() allows exploitation of a race condition during host interface detachment and listing, crashing the libvirt daemon and enabling endpoint denial of service via application or system exploitation.
