Sicherheit: Mehrere Probleme in dpdk
Red Hat Product Security has rated this update as having a security impact of
Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
The dpdk packages provide the Data Plane Development Kit, which is a set of
libraries and drivers for fast packet processing in the user space.
Security Fix(es):
* dpdk: dpdk: Missing memory size validation before mmap in vhost memory region
setup (CVE-2026-86561)
* dpdk: dpdk: Control-queue descriptor double-fetch overflows host heap in DPDK
vhost (VDUSE) (CVE-2026-86562)
* dpdk: dpdk: Double offset bug in vhost log mapping calculation
(CVE-2026-86563)
* dpdk: dpdk: Guest can desynchronize virtqueue size from inflight descriptor
table size, causing out-of-bounds write (CVE-2026-86565)
* dpdk: dpdk: Guest with runt RX descriptors underflows copy length in vhost
enqueue (split and packed rings) (CVE-2026-86566)
* dpdk: dpdk: VDUSE handler fails to invalidate vring pointers when IOTLB is
invalidated, leading to use-after-unmap (CVE-2026-86567)
* dpdk: dpdk: Guest-triggered use-after-free and type confusion in vhost-crypto
session cleanup (CVE-2026-86845)
* dpdk: dpdk: Guest can trigger out-of-bounds write by controlling avail ring
index in vhost-crypto (CVE-2026-86846)

cleanup (CVE-2026-86847)
* dpdk: dpdk: Time-of-check/time-of-use vulnerability allowing guest-triggered
out-of-bounds write in vhost-crypto (CVE-2026-86848)
* dpdk: dpdk: Integer overflow combined with missing validation leads to host
buffer overflow in vhost-crypto (CVE-2026-86849)
* dpdk: dpdk: Stack and heap buffer overflow in nfp vDPA driver
(CVE-2026-86856)
* dpdk: dpdk: Guest-triggered out-of-bounds walk via vhost indirect descriptor
length TOCTOU (CVE-2026-93683)
* dpdk: dpdk: heap out-of-bounds read/write in GSO header copy
(CVE-2026-100236)
