CVSS Release:
CVE-2022-49533: 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
The exploitability of CVE-2022-49533 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
No exploitability data is available for CVE-2022-49533.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2022-49533, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2022-49533, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.045% (probability of exploit)
EPSS Percentile: 18.4%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 81.6% of others.
