A fix has been implemented in the Linux kernel as indicated by the presence of fixed commit versions. Users should update to a kernel version that includes these fixes to resolve the issue.
Description
A vulnerability in the Linux kernel's vdpa ifcvf component caused devices with unsupported features to not be properly handled, potentially leading to inconsistent release of allocated device and adapter pointers. This issue has been resolved by routing unsupported provisioned features through a common error path after vdpa_alloc_device(), ensuring consistent resource release.
