CVE-2026-96582— Out-of-bounds Read via Check-after-use in the USBX HID Report Descriptor Parser
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.
HID 报告描述符是由一系列项目组成的序列，每个项目的头部都声明了其后续跟随的数据字节数。USBX 主机通过依次遍历每个头部并解析其后的数据来解析该序列。 在遍历过程中，系统仅在越过头部并解析完有效载荷后，才检查该项目是否位于描述符范围内；而其所依赖的项目分析逻辑，从未将声明的尺寸与实际接收到的字节数进行比对。因此，若某个 HID 外设返回了一个长度不足的报告描述符，就会在常规枚举过程中引发堆越界读取漏洞。

Vulnerability Title
Out-of-bounds Read via Check-after-use in the USBX HID Report Descriptor Parser
Source: CVE Program / CVE List V5
Vulnerability Description
A HID report descriptor is a sequence of items, each declaring in its header how many data bytes follow. The USBX host walks that sequence by advancing over each header and parsing the data behind it.
The walk checked that an item fitted in the descriptor only **after** it had advanced past the header and parsed the payload, and the item analysis it relied on never measured the declared sizes against the bytes actually received. A HID peripheral returning a short report descriptor therefore drove a heap out-of-bounds read during ordinary enumeration.
