Kernel-memory disclosure via improper Wi-Fi initialization
Published Jun 9, 2020 · Updated Aug 4, 2024
Improper initialization in the Wi-Fi subsystem in Apple macOS before Catalina 10.15.5 allows local users to read kernel memory. Apple's Wi-Fi component fails to initialize memory fully before making its contents readable, but Apple has not disclosed the affected function or data path. Exploitation requires local user access and yields kernel-memory disclosure without reported modification or service interruption.
