{"id":"AZL-77226","summary":"CVE-2026-23054 affecting package kernel for versions less than 6.6.126.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hv_netvsc: reject RSS hash key programming without RX indirection table\n\nRSS configuration requires a valid RX indirection table. When the device\nreports a single receive queue, rndis_filter_device_add() does not\nallocate an indirection table, accepting RSS hash key updates in this\nstate leads to a hang.\n\nFix this by gating netvsc_set_rxfh() on ndc-\u003erx_table_sz and return\n-EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device\ncapabilities and prevents incorrect behavior.","modified":"2026-08-28T17:47:42.789166267Z","published":"2026-02-04T17:16:16Z","upstream":["CVE-2026-23054"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23054"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-77226.json"}}],"schema_version":"1.9.0"}
