{"id":"CVE-2026-23054","summary":"net: hv_netvsc: reject RSS hash key programming without RX indirection table","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":"2026-04-02T17:29:34.309255179Z","published":"2026-02-04T16:04:23.396Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:0984-1","SUSE-SU-2026:1003-1","SUSE-SU-2026:1041-1","SUSE-SU-2026:1077-1","SUSE-SU-2026:1078-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:1131-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23054.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/11dd9a9ef4dc4507a15a69b8511a0013c6c28fa3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4cd55c609e85ae2313248ef1a33619a3eef44a16"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8288136f508e78eb3563e7073975999cf225a2f9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82c9039c8ebb715753a40434df714f865a3aec9c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d23564955811da493f34412d7de60fa268c8cb50"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23054.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23054"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"962f3fee83a4ef9010ae84dc43ae7aecb572e2a9"},{"fixed":"8288136f508e78eb3563e7073975999cf225a2f9"},{"fixed":"82c9039c8ebb715753a40434df714f865a3aec9c"},{"fixed":"4cd55c609e85ae2313248ef1a33619a3eef44a16"},{"fixed":"11dd9a9ef4dc4507a15a69b8511a0013c6c28fa3"},{"fixed":"d23564955811da493f34412d7de60fa268c8cb50"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23054.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.11.0"},{"fixed":"6.1.162"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.122"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.67"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23054.json"}}],"schema_version":"1.7.5"}
