CVE-2022-26697

Process-memory disclosure via AppleScript out-of-bounds read

Published May 26, 2022 · Updated Aug 3, 2024

An out-of-bounds read in AppleScript in Apple macOS allows local users to disclose process memory or crash an app via a crafted binary. The AppleScript component reads past a buffer boundary while processing insufficiently validated binary input; Apple has not disclosed the affected function. Another user must process the crafted file, after which the read can expose process memory or terminate the application.
