CVE-2026-13216 Out-of-bounds stack write in Zephyr virtio PCI driver from unvalidated device-supplied capability length

The virtio PCI driver drivers/virtio/virtiopci.c parses a device's PCI capability list during driver initialization. In virtiopcireadcap the device-supplied capability length byte caplen read from PCI config space via pcieconfread was only checked with asserttmp.caplen == capstructsize. That asse...

CVE-2026-13212

The Zephyr virtio driver does not validate the descriptor-chain head id that the virtio device writes into the used ring. In virtioisr drivers/virtio/virtiocommon.c, the device-written vq-used-ringidx.id is used directly as an index into vq-recvcbs and vq-desc, which are both allocated with exact...

CVE-2026-64490

A flaw was found in the Linux kernel's ALSA virtio sound driver. A malicious or buggy virtio device can provide invalid control metadata, such as an unknown control type or an oversized value count. The driver's control handling trusts this unvalidated metadata, leading to out-of-bounds access wh...
