Description
A flaw was found in the Linux kernel's IFCVF vDPA (vhost Data Path Acceleration) driver. When provisioning a device with unsupported features, the driver returns an error without routing through the cleanup path to free allocated device structures. A local privileged user could exploit this flaw by repeatedly attempting to create devices with invalid feature configurations, leading to a memory leak and potential Denial of Service (DoS) via resource exhaustion.
