If\nthe value is greater than zero, proceed with forwarding\nit to the firmware. However, if the value is invalid,\nreject the association request to prevent potential\nfirmware crashes.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/25a15f80253a7c8776e4e4880d797d20ec864154","https://git.kernel.org/stable/c/838c2cfdb6be7d7d8c06c711edf893eb34ca2e7c","https://git.kernel.org/stable/c/db163a463bb93cd3e37e1e7b10b9726fb6f95857"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-46827","score":0.00234,"percentile":0.14421,"date":"2026-11-01"},"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).
