RHEL 9 : dpdk (RHSA-2026:94629)

high Nessus Plugin ID 375542

Synopsis

The remote Red Hat host is missing one or more security updates for dpdk.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:94629 advisory.

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)

* dpdk: dpdk: Guest can trigger infinite loop in vhost-crypto writeback chain 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)
