A Red Hat only CVE-2020-12352 regression issue was found in the way the
Linux kernel’s Bluetooth stack implementation handled the initialization of
stack memory when handling certain AMP packets. This flaw allows a remote
attacker in an adjacent range to leak small portions of stack memory on the
system by sending specially crafted AMP packets. The highest threat from
this vulnerability is to data confidentiality.
