Vulnerabilities 14
-
High 8.8
Dpdk: dpdk: vduse handler fails to invalidate vring pointers when iotlb is invalidated, leading to use-after-unmap
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.
-
High 8.8
Dpdk: dpdk: time-of-check/time-of-use vulnerability allowing guest-triggered out-of-bounds write in 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.
-
High 8.6
Dpdk: dpdk: heap out-of-bounds read/write in gso header copy
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 GSO segment size can un…
-
High 8.2
Dpdk: dpdk: guest can desynchronize virtqueue size from inflight descriptor table size, causing out-of-bounds write
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.
-
High 7.8
Dpdk: dpdk: control-queue descriptor double-fetch overflows host heap in dpdk vhost (vduse)
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.
-
High 7.8
Dpdk: dpdk: double offset bug in vhost log mapping calculation
A flaw was found in DPDK lib/vhost. A double-offset bug in vhost log mapping calculation can lead to incorrect memory access.
-
Medium 6.5
Dpdk: dpdk: missing memory size validation before mmap in vhost memory region setup
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.
-
Medium 6.5
Dpdk: dpdk: guest with runt rx descriptors underflows copy length in vhost enqueue (split and packed rings)
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.
-
Medium 6.5
Dpdk: dpdk: guest-triggered use-after-free and type confusion in vhost-crypto session cleanup
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 vhost-crypto backend.
-
Medium 6.5
Dpdk: dpdk: guest can trigger out-of-bounds write by controlling avail ring index in 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.
-
Medium 6.5
Dpdk: dpdk: guest can trigger infinite loop in vhost-crypto writeback chain cleanup
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.
-
Medium 6.5
Dpdk: dpdk: integer overflow combined with missing validation leads to host buffer overflow in 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.
-
Medium 6.5
Dpdk: dpdk: stack and heap buffer overflow in 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.
-
Medium 6.4
Dpdk: dpdk: guest-triggered out-of-bounds walk via vhost indirect descriptor length toctou
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 changes the length between …
