{"id":"ALSA-2026:94630","summary":"Important: dpdk security update","details":"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.  \n\nSecurity Fix(es):  \n\n  * dpdk: dpdk: Missing memory size validation before mmap in vhost memory region setup (CVE-2026-86561)\n  * dpdk: dpdk: Control-queue descriptor double-fetch overflows host heap in DPDK vhost (VDUSE) (CVE-2026-86562)\n  * dpdk: dpdk: Double offset bug in vhost log mapping calculation (CVE-2026-86563)\n  * dpdk: dpdk: Guest can desynchronize virtqueue size from inflight descriptor table size, causing out-of-bounds write (CVE-2026-86565)\n  * dpdk: dpdk: Guest with runt RX descriptors underflows copy length in vhost enqueue (split and packed rings) (CVE-2026-86566)\n  * dpdk: dpdk: VDUSE handler fails to invalidate vring pointers when IOTLB is invalidated, leading to use-after-unmap (CVE-2026-86567)\n  * dpdk: dpdk: Guest-triggered use-after-free and type confusion in vhost-crypto session cleanup (CVE-2026-86845)\n  * dpdk: dpdk: Guest can trigger out-of-bounds write by controlling avail ring index in vhost-crypto (CVE-2026-86846)\n  * dpdk: dpdk: Guest can trigger infinite loop in vhost-crypto writeback chain cleanup (CVE-2026-86847)\n  * dpdk: dpdk: Time-of-check/time-of-use vulnerability allowing guest-triggered out-of-bounds write in vhost-crypto (CVE-2026-86848)\n  * dpdk: dpdk: Integer overflow combined with missing validation leads to host buffer overflow in vhost-crypto (CVE-2026-86849)\n  * dpdk: dpdk: Stack and heap buffer overflow in nfp vDPA driver (CVE-2026-86856)\n  * dpdk: dpdk: Guest-triggered out-of-bounds walk via vhost indirect descriptor length TOCTOU (CVE-2026-93683)\n  * dpdk: dpdk: heap out-of-bounds read/write in GSO header copy (CVE-2026-100236)\n\n\nFor more details about the security issue(s), including the impact, a CVSS score,
