For\nexample, on the AP side, if a station's setup link is the 5G link and\nthe station uses 2G to transmit a frame, the value of non_aql_packets\nis increased on the 5G wcid but decreased on the 2G wcid. Once the\ninflated counter exceeds MT_MAX_NON_AQL_PKT, the TX scheduler\npermanently refuses to service the station.\n\nDrop the reassignment and account on the wcid used for transmission.\nThis also records the actual wcid in the queue entry.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/186c957ac3325aefb982567ffdd3654b283688a7","https://git.kernel.org/stable/c/2c321f86846ead00552bc65f73f5b5f1f81d4023","https://git.kernel.org/stable/c/8ae659743ba936b22ecb4620815887728e2820d6","https://git.kernel.org/stable/c/f85f6933cc170155f1c7c2dffdd014965787c71b","https://git.kernel.org/stable/c/fc7fae55255ccbde009232e84b102d2782a69ecf"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90375","score":0.00168,"percentile":0.06152,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
