Summary

The Linux kernel Bluetooth ISO code copies Periodic Advertisement Report content into BASE without first checking that the service UUID is the Basic Audio Announcement Service UUID. An adjacent unauthenticated attacker can trigger this with low complexity, which affects confidentiality, integrity and availability.
