UBUNTU-CVE-2026-97994

In the Linux kernel, the following vulnerability has been resolved: vhost/vdpa: reject VRINGNUM larger than device max vhostvringsetnum accepts any non-zero power-of-two queue size that fits in 16 bits. vhost-vdpa then passes that value to setvqnum without comparing it with getvqnummax. A process...

In the Linux kernel, the following vulnerability has been resolved: vhost-vdpa: don't install the eventfdctxfdget error in configctx vhostvdpasetconfigcall swaps the eventfdctxfdget return value into v-configctx before checking it, so on failure the field briefly holds an ERRPTR: ctx = fd ==...

CVE-2026-97994

The Linux kernel contains a vulnerability in the vhost-vdpa component where vhost_vring_set_num() accepts a queue size that exceeds the device's maximum capacity without proper validation against get_vq_num_max(). A process with access to /dev/vhost-vdpa-* can exploit this to configure a queue la...
