CVE-2022-49533
7.8 · HIGHOverview
CVE-2022-49533 is a high-severity vulnerability affecting linux linux_kernel. It was published on February 26, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
