Short explanation

Eclipse ThreadX - USBX processes the VideoStreaming interface wTotalLength field without proper bounds checking, leading to out-of-bounds reads.

Why does it matter?

This vulnerability can lead to information disclosure and denial of service on systems exposed to untrusted physical devices and queries.

What should be done?

  • Review the vendor security advisory.
  • Update to unaffected versions.

Show the technical text from the sources

A VideoStreaming interface reports the size of its whole class-specific descriptor block in the `wTotalLength` field of its input header. The USBX host recorded that figure and used it as the budget for walking the format, frame and frame-interval descriptors, without holding it against the configuration descriptor actually received. A device that reports a `wTotalLength` larger than the descriptors it supplies therefore had its own claim believed. Once the real bytes ran out the walk kept going, dereferencing the cursor past the end of the configuration buffer, in the host's context, whenever the application queried format or frame data.
