CVE-2024-38078 is a use-after-free vulnerability classified under CWE-416, found in the Xbox Wireless Adapter component of Microsoft Windows 11 version 21H2 (build 10.0.0). Use-after-free vulnerabilities occur when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution or system crashes. This specific vulnerability enables remote code execution (RCE) without requiring any privileges or user interaction, which significantly increases the risk profile. However, the attack complexity is high, meaning exploitation requires specific conditions or expertise. The CVSS 3.1 base score is 7.5, reflecting high impact on confidentiality, integrity, and availability. The vulnerability is remotely exploitable (Attack Vector: Adjacent Network), but with high attack complexity and no privileges required. The scope is unchanged, meaning the vulnerability affects only the vulnerable component and does not extend beyond it. No known exploits are currently reported in the wild, and no patches have been released at the time of publication (July 2024). The Xbox Wireless Adapter is used to connect Xbox controllers wirelessly to Windows PCs, and this vulnerability could allow attackers to execute arbitrary code remotely, potentially taking full control of affected systems. The vulnerability was reserved in June 2024 and published in July 2024, indicating recent discovery and disclosure.

For European organizations, this vulnerability poses a significant risk, especially for those using Windows 11 version 21H2 in environments where Xbox Wireless Adapters are deployed. The potential for remote code execution without user interaction or privileges means attackers could compromise systems silently and gain full control, leading to data breaches, system disruption, or lateral movement within networks. Critical infrastructure, government agencies, and enterprises with high reliance on Windows 11 could face operational disruptions and data confidentiality breaches. The gaming industry and related sectors may also be targeted due to the specific component involved. The lack of a patch increases exposure time, and organizations may face compliance and reputational risks if exploited. Given the high attack complexity, widespread exploitation may be limited initially, but targeted attacks against high-value European entities are plausible.

1. Monitor Microsoft security advisories closely and apply patches immediately upon release. 2. Restrict network access to the Xbox Wireless Adapter service, especially on enterprise networks, using firewall rules and network segmentation. 3. Disable or uninstall the Xbox Wireless Adapter driver or service on systems where it is not required. 4. Implement strict endpoint detection and response (EDR) solutions to detect anomalous behavior related to wireless adapter usage or memory corruption exploits. 5. Conduct regular vulnerability assessments and penetration testing focusing on Windows 11 systems with wireless peripherals. 6. Educate IT staff about the vulnerability specifics to recognize potential exploitation attempts. 7. Limit the use of wireless peripherals in sensitive environments until patches are applied. 8. Employ network intrusion detection systems (NIDS) with updated signatures to detect potential exploitation attempts targeting this vulnerability.
