CVE-2025-59613
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 when output buffer size is smaller than input buffer size during data copying operation.
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 buffer overflow vulnerability exists where data is copied from an input buffer to an output buffer without verifying the output buffer is large enough to hold the input data. This can cause memory corruption by writing beyond the allocated output buffer boundaries, potentially leading to crashes or code execution in some contexts.

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 Qualcomm wireless or Fastconnect componentsCheck system information, device manager, or firmware inventory for Qualcomm wireless adapters, network cards, or Fastconnect software. Look for devices with names containing 'Qualcomm', 'Fastconnect', 'Cologne', 'Iqx', 'Qca', or 'Qcm'.Affected if Any of the following products are present: Qualcomm Cologne, Fastconnect 6700/6900/7800, Iqx5121, Iqx7181, Qca0000, or Qcm5430 firmware.
-
Determine firmware version of Qualcomm componentUse the vendor-provided tool (often called 'QCA', 'Qualcomm Firmware Tool', or device-specific firmware utility) to query the installed firmware version. This may be accessible via command line like 'firmware-tool --version' or through the device properties in system settings.Affected if The firmware version matches any of the listed product names (all versions of these products are affected).
-
Check for wireless/Fastconnect service or driverList running services or installed drivers related to Qualcomm wireless. On Linux, check 'lsmod' for wireless kernel modules and 'rfkill list' for wireless devices. On Windows, check Device Manager under Network Adapters.Affected if A Qualcomm wireless service, driver, or firmware component is active and matches the affected product list.
-
Verify wireless data path is accessibleThe vulnerability triggers when data is copied from input to output buffer. Check if the wireless interface is configured and active (can transmit/receive packets), as this enables the vulnerable code path.Affected if The Qualcomm wireless interface is enabled and capable of network communication.
If any Qualcomm Cologne, Fastconnect 6700/6900/7800, Iqx5121, Iqx7181, Qca0000, or Qcm5430 firmware is present and active, the environment is affected since all versions of these products contain the buffer size validation flaw.

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 explicit bounds checking to ensure the destination buffer is at least as large as the source before copying data, or use safe memory copy functions that automatically handle size mismatches.
