Summary

Eclipse ThreadX USBX from 0 through 6.5.1.202602 is affected. The PIMA/MTP host class reads past the end of a heap buffer when a device over-reports its object handle count (CWE-125). A malicious USB MTP or PTP device can trigger this during ordinary object enumeration, leaking adjacent heap contents to the application or faulting on an unmapped page.
