CVE-2020-25661

A Red Hat only CVE-2020-12351 regression issue was found in the way the Linux kernel's Bluetooth implementation handled L2CAP packets with A2MP CID. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or potentially executing arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
