> 9.2 CRITICAL

## Beschreibung

CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could

## Schwachstellen-Klasse

- **CWE-119** — Improper Restriction of Operations within the Bounds of a Memory Buffer
  The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
