CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-59206 is a high-severity Use After Free (CWE-416) vulnerability in Microsoft Windows 11 24H2. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 28th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and SI-16 (Memory Protection) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Directly counters the CWE-416 use-after-free by enforcing memory protections (DEP, ASLR, etc.) that block exploitation of the ReFS Deduplication Service.
Limits privileges granted to the ReFS Deduplication Service so that a successful EoP yields minimal additional rights.
Isolates the deduplication service into its own execution domain, reducing the ability of a memory corruption bug to affect kernel or other high-privilege components.

Secure SDLC practices directly incorporate memory-safety tooling and reviews that prevent most use-after-free defects.
Vulnerability identification processes can discover use-after-free issues via scanning or analysis but do not prevent their introduction.
Routine patching removes known use-after-free instances after they have been introduced in released software.

Security testing in development can detect use-after-free bugs before release.
Secure SDLC mandates memory-safety practices that reduce use-after-free defects.
Application security requirements can specify memory-management rules that mitigate use-after-free.
Secure architecture principles include memory-safety design choices that limit use-after-free exposure.
Secure coding standards directly prescribe avoidance of use-after-free patterns.
Change-management processes help ensure memory-safety fixes are deployed consistently.
