CVE-2024-38078 Overview
CVE-2024-38078 is a remote code execution vulnerability affecting the Xbox Wireless Adapter driver on Microsoft Windows 11. The flaw is rooted in a use-after-free condition [CWE-416] within the wireless adapter component. An adjacent-network attacker can trigger the flaw without authentication or user interaction. Successful exploitation results in arbitrary code execution in the context of the vulnerable driver.
Critical Impact
An unauthenticated attacker within wireless range can execute arbitrary code on affected Windows 11 systems by exploiting a use-after-free condition in the Xbox Wireless Adapter driver.

Technical Details for CVE-2024-38078
Vulnerability Analysis
The vulnerability resides in the Xbox Wireless Adapter driver stack shipped with Windows 11. The underlying weakness is a use-after-free [CWE-416], where memory referenced by the driver is freed but subsequently accessed. An attacker within radio range of the target can craft malicious wireless frames that manipulate the driver's memory state. Because the flaw is exploited before any authentication layer processes traffic, no user credentials are required.
Successful exploitation allows the attacker to influence execution flow inside the driver, which runs with high privileges. The attack complexity is rated high, indicating that reliable exploitation requires precise timing or environmental conditions. The Exploit Prediction Scoring System (EPSS) estimates the probability of exploitation at 0.696%.
Root Cause
The root cause is improper lifetime management of driver objects. The driver retains and dereferences a pointer to a memory region after that region has been released back to the allocator. When an attacker triggers the freed-object condition and then re-enters the affected code path, the driver operates on stale memory that may already contain attacker-controlled data.
Attack Vector
The attack vector is adjacent network access, meaning the attacker must be within wireless proximity of the target device. Exploitation requires the Xbox Wireless Adapter to be present and active on the target host. No user interaction is required, and no privileges on the target are necessary. Details of the exploitation technique are documented in the Microsoft Security Update Guide.
No public proof-of-concept exploit or exploitation in the wild has been confirmed for this vulnerability.
Detection Methods for CVE-2024-38078
Indicators of Compromise
- Unexpected crashes, bug checks, or restarts involving the Xbox Wireless Adapter driver on Windows 11 hosts
- Anomalous wireless traffic patterns targeting hosts with Xbox Wireless Adapters attached
- New or unsigned processes spawning shortly after wireless driver events in system logs
Detection Strategies
- Monitor Windows Event Log and WER (Windows Error Reporting) entries for driver faults referencing the Xbox Wireless Adapter
- Correlate kernel crash telemetry with proximity-based network events to identify potential exploitation attempts
- Track installed driver versions across the fleet and flag systems running unpatched versions on affected Windows 11 builds
Monitoring Recommendations
- Enable and forward kernel-mode crash telemetry to a centralized log store for analysis
- Baseline normal wireless adapter activity and alert on deviations, especially unauthenticated frame-processing errors
- Continuously inventory Xbox Wireless Adapter presence and driver versions on Windows 11 endpoints
How to Mitigate CVE-2024-38078
Immediate Actions Required
- Apply the Microsoft security update referenced in the Microsoft Security Update Guide for CVE-2024-38078 to all affected Windows 11 21H2, 22H2, and 23H2 systems
- Prioritize patching for endpoints that actively use Xbox Wireless Adapters or operate in shared wireless environments
- Audit endpoint inventory to identify Windows 11 hosts with Xbox Wireless Adapter hardware attached
Patch Information
Microsoft has issued a security update for CVE-2024-38078. Administrators should install the update via Windows Update or WSUS. Detailed patch information is available at the Microsoft Security Update Guide.
Workarounds
- Physically disconnect the Xbox Wireless Adapter from systems that cannot be patched immediately
- Disable the Xbox Wireless Adapter driver in Device Manager on hosts where the peripheral is not required
- Restrict use of Xbox Wireless Adapters to trusted physical environments away from untrusted wireless actors
# Configuration example: disable the Xbox Wireless Adapter device via PowerShell
