CVE-2024-44145

Lock Screen bypass via Sidecar state handling

Published Oct 28, 2024 · Updated Apr 2, 2026

Lock Screen bypass in Apple Sidecar before macOS 15 and iOS and iPadOS 18 allows physically proximate attackers to access a locked Mac. Sidecar session state management fails to preserve the Mac's locked state while an iPad acts as its display; Apple has not disclosed the responsible function or state transition. Exploitation requires physical access to a supported Mac with Sidecar enabled and an associated iPad, and Apple reports Lock Screen bypass rather than a network-reachable attack.
