Name: Attempt to Access Child of a Non-structure Pointer

Casting a non-structure type to a structure type and accessing a field can lead to memory access errors or data corruption.

General Informations

Modes Of Introduction

Implementation

Common Consequences

Scope Impact Likelihood
IntegrityModify Memory

Note: Adjacent variables in memory may be corrupted by assignments performed on fields after the cast.
AvailabilityDoS: Crash, Exit, or Restart

Note: Execution may end due to a memory access error.

Observed Examples

References Description

CVE-2021-3510

JSON decoder accesses a C union using an invalid offset to an object

Potential Mitigations

Phases : Requirements
The choice could be made to use a language that is not susceptible to these issues.
Phases : Implementation
Review of type casting operations can identify locations where incompatible types are cast.

Vulnerability Mapping Notes

Justification : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
