CVE-2022-42789Public exploit

Sensitive-data access via Rosetta AOT cache poisoning

Published Nov 1, 2022 · Updated Aug 3, 2024

Code-signature validation failure in AppleMobileFileIntegrity in Apple macOS before 11.7, 12.6, or 13 allows local users to read sensitive data. Rosetta 2 derived a signed x86_64 executable's AOT cache lookup from mutable file metadata, allowing code to be changed on a FAT32 image, translated, and restored while retaining a cache match. Exploitation requires a user to execute a crafted x86_64 app on an Apple silicon Mac with Rosetta 2; the poisoned translation runs with the trusted app's access to protected user data.
