USN-4463-1 Not scored

linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon vulnerabilities

It was discovered that the bcache subsystem in the Linux kernel did not properly release a lock in some error conditions. A local attacker could possibly use this to cause a denial of service. (CVE-2020-12771) Kyungtae Kim discovered that the USB testing driver in the Linux kernel did not properly deallocate memory on disconnect events. A physically proximate attacker could use this to cause a denial of service (memory exhaustion). (CVE-2020-15393)
