CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-787Out-of-bounds Write17,600+Out-of-bounds writes that corrupt control flow or inject shellcode are rendered non-executable by the same memory protections.
CWE-119Improper Restriction of Operations within the Bounds of a Memory Buffer14,700+Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
CWE-416Use After Free10,900+Use-after-free exploits that achieve arbitrary code execution are blocked or significantly hardened by non-executable pages and ASLR.
CWE-94Improper Control of Generation of Code ('Code Injection')7,800+Directly prevents execution of attacker-supplied code written into data memory regions.
CWE-123Write-what-where Condition66Write-what-where primitives are neutralized when the attacker cannot execute the memory they control.
