CVE-2022-21240 is a medium-severity vulnerability affecting certain Intel(R) PROSet/Wireless WiFi products. The issue stems from an out-of-bounds read condition (classified under CWE-125), which allows a privileged local user to potentially disclose sensitive information. Specifically, the vulnerability occurs when the software improperly accesses memory beyond the intended buffer boundaries, leading to leakage of information that could be leveraged for further attacks or reconnaissance. Exploitation requires local access with high privileges (e.g., administrator or SYSTEM level) and does not require user interaction. The vulnerability does not impact the integrity or availability of the system but compromises confidentiality by exposing potentially sensitive data. The CVSS v3.1 base score is 4.4, reflecting a moderate risk primarily due to the requirement for local privileged access and the limited scope of impact. No known exploits are currently reported in the wild, and no patches are explicitly linked in the provided data, though Intel typically addresses such issues in driver or software updates. The affected products are Intel PROSet/Wireless WiFi software components, which are commonly used to manage Intel wireless adapters on Windows platforms. This vulnerability highlights the importance of secure memory handling in device drivers and associated management software.

For European organizations, the primary impact of CVE-2022-21240 lies in the potential exposure of sensitive information on systems using affected Intel wireless drivers. Since exploitation requires local privileged access, the threat is more relevant in scenarios where an attacker has already gained elevated access or where insider threats exist. Confidentiality breaches could lead to leakage of credentials, configuration data, or other sensitive information stored or processed by the wireless management software. This could facilitate lateral movement or privilege escalation in corporate networks. Given the widespread use of Intel wireless adapters in enterprise laptops and desktops across Europe, organizations with inadequate endpoint security or insufficient privilege management could be at risk. However, the lack of remote exploitability and the need for high privileges limit the immediate threat level. Still, in regulated sectors such as finance, healthcare, and government, even moderate confidentiality leaks can have significant compliance and reputational consequences.

To mitigate CVE-2022-21240, European organizations should: 1) Ensure all Intel PROSet/Wireless WiFi software and drivers are updated to the latest versions provided by Intel or OEM vendors, as patches addressing this vulnerability are likely included in recent releases. 2) Enforce strict local privilege management by limiting administrative rights to trusted personnel and employing the principle of least privilege to reduce the risk of local exploitation. 3) Implement endpoint protection solutions that monitor and restrict unauthorized local access or suspicious activities involving wireless driver components. 4) Conduct regular audits of installed wireless drivers and software versions across the enterprise to identify and remediate vulnerable instances. 5) Educate IT staff and users about the risks of privilege escalation and insider threats, emphasizing the importance of secure credential management. 6) Consider application whitelisting or driver integrity verification mechanisms to prevent unauthorized modifications or loading of vulnerable drivers. These measures collectively reduce the attack surface and the likelihood of successful exploitation.
