Doc Text:
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.

Description OSIDB Bzimport 2026-09-25 11:13:19 UTC
In the Linux kernel, the following vulnerability has been resolved:

vdpa: ifcvf: Put device on unsupported feature error

Route unsupported provisioned features through the common error path after
vdpa_alloc_device() so the allocated device and adapter pointer are
released consistently.
