Memory and Storage Issues

A category in the Common Weakness Enumeration published by The MITRE Corporation.


Summary

Categories in the Common Weakness Enumeration (CWE) group entries based on some common characteristic or attribute.

Weaknesses in this category are typically associated with memory (e.g., DRAM, SRAM) and storage technologies (e.g., NAND Flash, OTP, EEPROM, and eMMC).

Weaknesses

Assumed-Immutable Data is Stored in Writable Memory

Immutable data, such as a first-stage bootloader, device identifiers, and "write-once" configuration settings are stored in writable memory that can be re-programmed o...

Improper Access Control Applied to Mirrored or Aliased Memory Regions

Aliased or mirrored memory regions in hardware designs may have inconsistent read/write permissions enforced by the hardware. A possible result is that an untrusted ag...

Improper Write Handling in Limited-write Non-Volatile Memories

The product does not implement or incorrectly implements wear leveling operations in limited-write non-volatile memories.

Mirrored Regions with Different Values

The product's architecture mirrors regions without ensuring that their contents always stay in sync.

Sensitive Information in Resource Not Removed Before Reuse

When a device releases a resource such as memory or a file for reuse by other entities, information contained in the resource is not fully cleared prior to reuse of th...

Hardware Design

This view organizes weaknesses around concepts that are frequently used or encountered in hardware design. Accordingly, this view can align closely with the perspectiv...
