    Summary: linux, linux-hwe, linux-hwe-5.4, linux-oem, linux-raspi, linux-raspi-5.4, linux-snapdragon vulnerabilities

    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.
