Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-125 and the CVSS impact.

Summary

Apple iOS and iPadOS, macOS, tvOS, visionOS and watchOS versions before 27 are affected. An out-of-bounds read (CWE-125) occurs when processing a maliciously crafted Bluetooth packet. Apple fixed it with improved bounds checking. A remote unauthenticated attacker can send such a packet, but the processing requires user interaction, and successful exploitation discloses process memory.
