CVE-2026-23054

Published Feb 4, 2026

Overview

CVE-2026-23054 is a known-severity vulnerability. It was published on February 4, 2026.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

net: hv_netvsc: reject RSS hash key programming without RX indirection table

RSS configuration requires a valid RX indirection table. When the device

reports a single receive queue, rndis_filter_device_add() does not

allocate an indirection table, accepting RSS hash key updates in this

state leads to a hang.

Fix this by gating netvsc_set_rxfh() on ndc->rx_table_sz and return

-EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device

capabilities and prevents incorrect behavior.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
