Extended Description
In flat address space situations, never allow computing memory addresses as offsets from another memory address.
Fully specify protocol layout unambiguously, providing a structured grammar (e.g., a compilable yacc grammar).
Testing: Test that the implementation properly handles each case in the protocol grammar.
No detection method information available for this CWE.
No examples or observed CVEs available for this CWE.

CWE-188: Reliance on Data/Memory Layout is a Common Weakness Enumeration (CWE) entry maintained by MITRE. Description Extended Description
If exploited, CWE-188 (Reliance on Data/Memory Layout) it can compromise Modify Memory and Read Memory, leading to outcomes such as Scope: Integrity and Confidentiality Can result in unintended modifications or exposure of sensitive memory..
Recommended mitigations for CWE-188 include: In flat address space situations, never allow computing memory addresses as offsets from another memory address. Fully specify protocol layout unambiguously, providing a structured grammar (e.g., a compilable yacc grammar). Testing: Test that the implementation properly handles each case in the protocol grammar.
CWE-188 commonly affects Languages. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.
A CWE (Common Weakness Enumeration) like CWE-188 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
