CVE-2025-47399
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMemory Corruption while processing IOCTL call to update sensor property settings with invalid input parameters.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA memory corruption vulnerability exists in the IOCTL handler for sensor property settings. When processing IOCTL calls to update sensor properties with invalid or malformed input parameters, the handler fails to properly validate input lengths or bounds before copying data into memory buffers, leading to heap or stack corruption that could be exploited for privilege escalation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify affected Qualcomm firmware componentsDetermine if your system contains any of the following firmware modules: Qualcomm Cologne, Fastconnect 7800, Wcd9378c, Wsa8840, Wsa8845, Wsa8845h, X2000077, or X2000086. Check firmware manifests, driver listings, or system information utilities that enumerate loaded firmware modules.Affected if Any of the listed firmware components are present in the environment
-
Check sensor IOCTL handler statusInspect system configuration or driver settings to determine whether the sensor property IOCTL handler is enabled and accessible. This may involve checking driver debug interfaces, system logs, or configuration files related to sensor drivers.Affected if The sensor IOCTL handler for sensor property settings is actively loaded or accessible on the system
-
Verify sensor driver is processing IOCTL requestsMonitor system calls or driver communications for any IOCTL calls related to sensor property updates. Check driver debug logs or instrumentation if available for sensor property set operations.Affected if The system is processing IOCTL calls to update sensor properties through the vulnerable handler
A system is affected if it contains any of the listed Qualcomm firmware components and has the sensor property IOCTL handler enabled and actively processing requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement rigorous input validation and bounds checking in the IOCTL handler for sensor property updates; validate all input parameters (sizes, pointers, ranges) before any memory operations and reject requests with invalid parameters.
