https://www.bleepingcomputer.com/news/security/many-bluetooth-implementations-and-os-drivers-affected-by-crypto-bug/ > A cryptographic bug affects the Bluetooth implementations and operating system drivers of Apple, Broadcom, Intel, Qualcomm, and possibly other hardware vendors. > This bug occurs because Bluetooth-capable devices do not sufficiently validate encryption parameters used during "secure" Bluetooth connections. More precisely, pairing devices do not sufficiently validate elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange.
