Vendor Workaround
A viable mitigation for this vulnerability is to disable RSS on the nic/virtio driver. This can be performed either with the following qemu-kvm command "-device virtio-net-pci,rss=off", or, alternatively, by directly modifying the KVM XML file to disable RSS using a standard configuration tool (ex. libvirt).

EUVD |
EUVD-2024-47589 | A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host. |
