CVE-2025-7427

Local code execution via DLL search-path hijacking

Published Jul 22, 2025 · Updated Feb 26, 2026

Uncontrolled DLL search paths in Arm Development Studio before 2025 allow local users to execute code in the current user's context. Arm has not disclosed the executable, library name, or searched directory responsible for loading an attacker-controlled DLL. Exploitation requires a crafted DLL in a searched location, and the resulting code inherits the application's user privileges.
