CVE-2026-13216

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-2026-13216

CVE-2026-13216 is an out-of-bounds stack write in the Zephyr RTOS virtio PCI driver (drivers/virtio/virtio_pci.c). The device-supplied cap_len field, read from PCI config space, was validated only by a compiled-out assert() (gated by CONFIG_ASSERT, off by default in production). The unvalidated l...

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-2026-74684

A flaw was found in the Linux kernel's net: tap module. A NULL pointer dereference can occur in the tapgetuserxdp function when processing an XDP buffer with a GSO virtio-net header and a zero protocol. This can be triggered by a malicious guest in a virtualized environment, leading to a system...

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-2026-13212

The Zephyr RTOS virtio driver contains an out-of-bounds read in virtio_isr() (drivers/virtio/virtio_common.c). The device-written descriptor-chain head id from the used ring is used directly as an index into recv_cbs[] and desc[] without a bounds check. A malicious or compromised virtio backend (...

CVE-2026-74614

A flaw was found in the Linux kernel's vsock/virtio component. During system suspend and resume operations, a worker process might incorrectly retain a pointer to a deleted virtual queue while observing a replacement queue's running state. This inconsistent state can lead to system instability or...
