# CVE-2026-96582

> 4.9 MEDIUM · 🧪 PoC

## Beschreibung

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.

## Schwachstellen-Klasse

- **CWE-125** — Out-of-bounds Read
  The product reads data past the end, or before the beginning, of the intended buffer.
- **CWE-1285** — Improper Validation of Specified Index, Position, or Offset in Input
  The product receives input that is expected to specify an index, position, or offset into an indexable resource such as a buffer or file, but it does not validate or incorrectly validates that the specified index/position/offset has the required properties.
