ALSA-2022:8263 — Important: dpdk security and bug fix update

Affected: AlmaLinux:9: dpdk, AlmaLinux:9: dpdk-devel, AlmaLinux:9: dpdk-doc, AlmaLinux:9: dpdk-tools

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: DoS when a Vhost header crosses more than two descriptors and exhausts all mbufs (CVE-2022-2132) * DPDK: out-of-bounds read/write in vhost_user_set_inflight_fd() may lead to crash (CVE-2021-3839) * dpdk: error recovery in mlx5 driver not handled properly, allowing for denial of service (CVE-2022-28199)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

fkie_cve-2021-3839

A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate `msg->payload.inflight.num_queues`, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability.

OESA-2022-1713 — dpdk security update

Affected: openEuler:20.03-LTS-SP1: dpdk, openEuler:20.03-LTS-SP3: dpdk, openEuler:22.03-LTS: dpdk

DPDK core includes kernel modules, core libraries and tools. testpmd application allows to test fast packet processing environments on arm64 platforms. For instance, it can be used to check that environment can support fast path applications such as 6WINDGate, pktgen, rumptcpip, etc. More libraries are available as extensions in other packages. Security Fix(es): It’s an issue in the handling of vhost-user inflight type messages. A malicious vhost-user master can attach an unexpected number of fds as ancillary data to VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD messages that are not closed by the vhost-user slave. By sending such messages continuously, the vhost-user master could exhaust available fd in the vhost-user slave process and lead to a DoS.(CVE-2022-0669) In DPDK Vhost communication, we didn’t test if msg->payload.inflight.num_queues is out of bounds in function ‘vhost_user_set_inflight_fd()’, and could cause the program to write OOB.(CVE-2021-3839)
