CVE-2026-23054: net: hv_netvsc: reject RSS hash key programming without RX indirection table

—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 11dd9a9ef4dc4507a15a69b8511a0013c6c28fa3, 4cd55c609e85ae2313248ef1a33619a3eef44a16, 8288136f508e78eb3563e7073975999cf225a2f9.

Low priority for now. Upgrade to Linux Linux 11dd9a9ef4dc4507a15a69b8511a0013c6c28fa3, 4cd55c609e85ae2313248ef1a33619a3eef44a16, 8288136f508e78eb3563e7073975999cf225a2f9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
