When copying the SSIDs into the\nscan_req_params structure in the ath11k_mac_op_hw_scan route, it can\noverwrite the extraie pointer.\n\nFirmware supports 16 ssid * 4 bssid, for each ssid 4 bssid combo probe\nrequest will be sent, so totally 64 probe requests supported. So\nset both max ssid and bssid to 16 and 4 respectively. Remove the\nredundant macros of ssid and bssid.\n\nTested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01300-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/210505788f1d243232e21ef660efcd4838890ce8","https://git.kernel.org/stable/c/50dc9ce9f80554a88e33b73c30851acf2be36ed3","https://git.kernel.org/stable/c/ec5dfa1d66f2f71a48dab027d26a9fa78eb0f58f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49533","score":0.00295,"percentile":0.22132,"date":"2026-10-31"},"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).
