CVE-2022-49533

EUVD-2022-54476
In the Linux kernel, the following vulnerability has been resolved:

ath11k: Change max no of active probe SSID and BSSID to fw capability

The maximum number of SSIDs in a for active probe requests is currently
reported as 16 (WLAN_SCAN_PARAMS_MAX_SSID) when registering the driver.
The scan_req_params structure only has the capacity to hold 10 SSIDs.
This leads to a buffer overflow which can be triggered from
wpa_supplicant in userspace. When copying the SSIDs into the
scan_req_params structure in the ath11k_mac_op_hw_scan route, it can
overwrite the extraie pointer.

Firmware supports 16 ssid * 4 bssid, for each ssid 4 bssid combo probe
request will be sent, so totally 64 probe requests supported. So
set both max ssid and bssid to 16 and 4 respectively. Remove the
redundant macros of ssid and bssid.
