CVE-2022-42854

Kernel-memory disclosure via Bluetooth memory mishandling

Published Dec 15, 2022 · Updated Apr 21, 2025

Memory disclosure in Bluetooth on Apple macOS Monterey before 12.6.2 and Ventura before 13.1 allows local users to read kernel memory. Apple states only that improved memory handling corrected the Bluetooth issue and has not disclosed the faulty operation or code locus. A local app must execute on the Mac; the demonstrated consequence is exposure of kernel memory, with no published integrity or availability impact.
