CVE-2026-96402— USBX PIMA/MTP host class reads past its receive buffer when a device over-reports its object handle count
Quick assessment
Affected
Eclipse Foundation Eclipse ThreadX - USBX
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
恶意的 USB MTP/PTP 设备可在常规对象枚举过程中，诱使 USBX 主机读取堆缓冲区之后的内存区域，从而向应用程序泄露相邻的堆内容，或因访问未映射的页面而导致系统故障。
