Incorrect access of indexable resource ('range error') in Windows Sensor Data Service allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows Sensor Data Service allows an authenticated low-privileged user to gain full SYSTEM-level control on affected Windows 10, Windows 11, and Windows Server (2019-2025) systems. The flaw stems from incorrect access to an indexable resource (a range/bounds error, CWE-118) and yields high confidentiality, integrity, and availability impact per the CVSS 7.8 vector. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but Microsoft has released a patch.
Technical ContextAI
The Windows Sensor Data Service (SensorDataService) is a Windows component responsible for collecting and managing data from device sensors (accelerometers, ambient light, orientation, etc.) and exposing it to applications. This vulnerability is classified as CWE-118 (Incorrect Access of Indexable Resource, a 'range error'), meaning the service references an array, buffer, or indexable structure using an index that falls outside the intended bounds. In a privileged local service, such out-of-bounds access can corrupt memory or manipulate objects the caller should not control, enabling a low-privileged process to influence execution in the service's higher-privilege context. The CPE data confirms the affected surface is the Windows operating system itself across client (Windows 10 1809/21H2/22H2, Windows 11 24H2/25H2/26H1) and server (Windows Server 2019, 2022, 2025, including Server Core) SKUs.
RemediationAI
Patch available per vendor advisory: apply the Microsoft security update for CVE-2026-50367 delivered through the standard monthly cumulative update for your specific Windows build, as documented at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-50367 (the exact fixed build number is enumerated there per SKU and was not included in this dataset, so verify the KB against your version). Prioritize multi-user and shared systems (terminal/RDS servers, jump hosts) where untrusted low-privileged users can run code. If immediate patching is not possible, a compensating control is to restrict local logon and code-execution rights to trusted users and, where the sensor stack is not needed (typical for servers and VMs), consider disabling the Sensor Data Service (SensorDataService) - the trade-off is loss of sensor-dependent features such as automatic screen rotation, adaptive brightness, and location/orientation-aware apps, which is usually acceptable on servers but disruptive on tablets and convertibles.
