CVE-2026-23054

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: hv_netvsc: reject RSS hash key programming without RX indirection table<br /> <br /> RSS configuration requires a valid RX indirection table. When the device<br /> reports a single receive queue, rndis_filter_device_add() does not<br /> allocate an indirection table, accepting RSS hash key updates in this<br /> state leads to a hang.<br /> <br /> Fix this by gating netvsc_set_rxfh() on ndc-&gt;rx_table_sz and return<br /> -EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device<br /> capabilities and prevents incorrect behavior.
