ath11k: Change max no of active probe SSID and BSSID to fw capability
FAQ
Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

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. Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01300-QCAHKSWPL_SILICONZ-1
