CVE-2024-25388
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 · unediteddrivers/wlan/wlan_mgmt,c in RT-Thread through 5.0.2 has an integer signedness error and resultant buffer overflow.
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 confidenceThe WLAN management driver (drivers/wlan/wlan_mgmt.c) in RT-Thread operating system through version 5.0.2 contains an integer signedness error that leads to a buffer overflow vulnerability. This type of flaw occurs when a variable is incorrectly treated as signed instead of unsigned (or vice versa), causing unexpected memory access and potential memory corruption.

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 the RT-Thread version in your environmentCheck the version.h header file or build system output for the RT-Thread version number. Common locations include include/rtdef.h or version information displayed during boot.Affected if The version is 5.0.2 or lower
-
Verify the WLAN management driver is included in your buildInspect your build artifacts or source tree for the presence of drivers/wlan/wlan_mgmt.c or a compiled WLAN management module.Affected if The WLAN driver source file is present in your RT-Thread build
-
Confirm WLAN functionality is enabled in your configurationReview your RT-Thread configuration (typically via Kconfig or rtconfig.h) for WLAN-related settings such as RT_USING_WLAN or WLAN device enable options.Affected if WLAN or WiFi support is explicitly enabled in your configuration
-
Check for WLAN device registration in your systemExamine your application or system initialization code for calls to wlan_mgmt_init or WLAN device registration functions.Affected if Your system initializes or uses WLAN management interfaces
You are affected if your RT-Thread version is 5.0.2 or lower AND the WLAN management driver is present and actively used in your environment.

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 dataUpgrade RT-Thread to a version beyond 5.0.2 once the patch is available. Additionally, implement proper input validation and bounds checking in the WLAN driver to prevent buffer overflows.
