Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-36036 is an elevation-of-privilege vulnerability in the Windows Cloud Files Mini Filter Driver. The flaw, assigned CVSS 7.8, stems from out-of-bounds writes (CWE-122 and CWE-787) that allow an attacker who already possesses local access to corrupt memory and escalate privileges to SYSTEM level.
A local, authenticated user with low privileges can exploit the driver without user interaction, achieving full control over confidentiality, integrity, and availability on the affected Windows system. The attack requires only standard user rights and does not need network access or elevated credentials to begin.
Microsoft’s security update guide addresses the issue with patches released on 14 November 2023; administrators are advised to apply the updates through Windows Update or the Microsoft Update Catalog. The vulnerability also appears in CISA’s Known Exploited Vulnerabilities catalog, confirming observed in-the-wild exploitation and underscoring the need for prompt remediation.
EPSS scores have remained low, with a current value of 0.0152 and a peak of 0.0173, indicating limited but non-zero public interest following disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Out-of-bounds writes that corrupt control flow or inject shellcode are rendered non-executable by the same memory protections.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure-development practices directly require bounds checking and safe memory handling that prevent heap overflows.
Vulnerability scanning and recording can discover heap-overflow flaws but does not prevent their introduction in code.
Timely patching removes known heap-overflow instances after they exist.

Security testing in development and acceptance can detect heap overflows before release.
Secure development lifecycle mandates practices that reduce the likelihood of introducing heap overflows.
Application security requirements can specify bounds-checking and safe memory APIs that mitigate heap overflows.
Secure architecture and engineering principles include memory-safety and input-validation controls that address heap overflows.
Secure coding standards directly prescribe techniques (safe functions, bounds checks) that prevent heap-based buffer overflows.
Change management can enforce review gates that catch unsafe memory operations before deployment.
