CVE-2026-86856Medium· 6.5A flaw was found in the DPDK nfp vDPA driver
A flaw was found in the DPDK nfp vDPA driver. Stack and heap buffers sized for a single queue pair can be overflowed when more virtqueues are configured, leading to a host crash or memory corruption.
CVE-2026-86849Medium· 6.5A flaw was found in DPDK lib/vhost vhost-crypto
A flaw was found in DPDK lib/vhost vhost-crypto. Integer overflow in chain length checks, and missing length checks on the RSA path, can overflow a host buffer in the vhost-crypto backend.
CVE-2026-86848High· 8.8A flaw was found in DPDK lib/vhost vhost-crypto
A flaw was found in DPDK lib/vhost vhost-crypto. The indirect-descriptor snapshot double-fetches a guest descriptor next index, allowing a malicious guest to cause an out-of-bounds access in the host backend.
CVE-2026-86847Medium· 6.5A flaw was found in DPDK lib/vhost vhost-crypto
A flaw was found in DPDK lib/vhost vhost-crypto. Write-back chain cleanup can follow an uninitialized next pointer when mapping a guest descriptor fails, causing the host vhost-crypto process to hang or crash.
CVE-2026-86846Medium· 6.5A flaw was found in DPDK lib/vhost vhost-crypto
A flaw was found in DPDK lib/vhost vhost-crypto. A guest can supply an avail-ring descriptor index that is used without bounds checking, causing an out-of-bounds write in the host vhost-crypto backend.
CVE-2026-86845Medium· 6.5A flaw was found in DPDK lib/vhost vhost-crypto
A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vho…
CVE-2026-86567High· 8.8A flaw was found in DPDK lib/vhost
A flaw was found in DPDK lib/vhost. The VDUSE handler fails to invalidate vring pointers when the IOTLB is invalidated, leading to use-after-unmap.
CVE-2026-86566Medium· 6.5A flaw was found in DPDK lib/vhost
A flaw was found in DPDK lib/vhost. A guest with runt RX descriptors can underflow the copy length in vhost enqueue, causing a denial of service in a shared vhost backend such as OVS-DPDK.
CVE-2026-86565High· 8.2A flaw was found in DPDK lib/vhost
A flaw was found in DPDK lib/vhost. A guest can desynchronize virtqueue size from inflight descriptor table size, causing an out-of-bounds write in the host vhost process.
CVE-2026-86563High· 7.8A flaw was found in DPDK lib/vhost
A flaw was found in DPDK lib/vhost. A double-offset bug in vhost log mapping calculation can lead to incorrect memory access.
CVE-2026-86562High· 7.8A flaw was found in DPDK lib/vhost
A flaw was found in DPDK lib/vhost. A TOCTOU double-fetch of control-queue descriptors allows a heap buffer overflow with attacker-controlled content in the VDUSE control-queue handler.
CVE-2026-100236High· 8.6A flaw was found in the DPDK GSO library
A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured G…
CVE-2026-93683Medium· 6.4A flaw was found in the DPDK vhost library
A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that chang…
CVE-2026-86561Medium· 6.5A flaw was found in DPDK lib/vhost
A flaw was found in DPDK lib/vhost. Memory size is not adequately validated before mmap during vhost memory-region setup, which can lead to a host crash or memory corruption.
