Kernel-memory disclosure or system termination via out-of-bounds read
Published Apr 1, 2020 · Updated Aug 4, 2024
Out-of-bounds read in Apple macOS Bluetooth before Catalina 10.15.4 allows local users to read kernel memory or terminate the system. The Bluetooth component insufficiently validates input before reading beyond the intended buffer, although Apple has not disclosed the exact parsing locus. Local access is required, and successful triggering is bounded to kernel-memory disclosure or unexpected system termination.
