Local memory disclosure via Wi-Fi input validation
Published May 26, 2022 · Updated Aug 3, 2024
Memory corruption in the Wi-Fi component of macOS Big Sur before 11.6.6 allows local users to disclose restricted memory via a malicious app. The Wi-Fi component inadequately validates application-controlled input before an out-of-bounds write, although Apple has not identified the affected function or input structure. Execution of a malicious local application and user interaction are required; the reported consequence is restricted-memory disclosure without integrity or availability impact.
