CVE-2022-28199Network attack vector

Network-interface denial of service via failed mlx5 recovery

Published Sep 1, 2022 · Updated Aug 3, 2024

Improper quantity validation in the MLNX_DPDK mlx5 network stack in NVIDIA FLARE allows remote authenticated users to interrupt service. After an mlx5 driver failure, the network stack mishandles error recovery and can leave the network interface in an unrecoverable state. Exploitation requires low privileges and traffic reaching an affected mlx5-backed data plane; the vendor assessment limits the demonstrated impact to availability.
