Details

Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux
kernel contained a type-confusion error. A physically proximate remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2020-12351)

Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux
kernel did not properly initialize memory in some situations. A physically
proximate remote attacker could use this to expose sensitive information
(kernel memory). (CVE-2020-12352)
