CVE-2025-43379

Protected-data disclosure via improper symlink validation

Published Nov 4, 2025 · Updated Nov 4, 2025

Symlink validation in AppleMobileFileIntegrity in Apple operating systems allows local users to read protected user data through an app. AppleMobileFileIntegrity follows a crafted symbolic link without adequately validating its destination before file access, allowing an app-controlled path to resolve into protected storage. Local code execution as an app is required, and the disclosed consequence is limited to reading protected user data.
