** Description changed: It was found that kvm_vm_ioctl_assign_device function did not check if the user requesting assignment was privileged or not. Together with /dev/kvm being 666, unprivileged user could assign unused pci devices, or even devices that were in use and whose resources were not properly claimed by the respective drivers. Please note that privileged access was still needed to re-program the device to for example issue DMA requests. This is typically achieved by touching files on sysfs filesystem. These files are usually not accessible to unprivileged users. As a result, local user could use this flaw to crash the system. + + Break-Fix: - 3d27e23b17010c668db311140b17bbbb70c78fb9
