CVE-2024-44253Public exploit

Protected-file modification via temporary mount-point race

Published Oct 28, 2024 · Updated Apr 2, 2026

Authorization bypass in macOS Ventura before 13.7.1, Sonoma before 14.7.1, and Sequoia before 15.1 allows local users to modify protected files. The RecoveryHDUpdate.pkg replaceRecovery script extracts and mounts attacker-replaceable disk images beneath /tmp, then trusts the user-controlled mount point while running with installer privileges. A local app can race the installer, replace the mount point with a symlink, and overwrite the SIP-protected TCC compatibility allowlist to obtain protected-data access.
