BleedingTooth: Linux Bluetooth Zero-Click Remote Code Execution

Note that Intel's advisory has since been corrected to say "All Linux kernel versions before 5.10 that support BlueZ" are affected. The fix is not in 5.9 nor any stable, so this is essentially a 0day.

That is what happens with monolithic kernels.

Worth noting the fix has been sent to linux-next instead and distros were not informed: https://twitter.com/mjg59/status/1316484882877435904
