Summary
linux-hwe, linux-aws-5.3, linux-azure-5.3, linux-gke-5.3 vulnerabilities
Details

It was discovered that the XFS file system implementation in the Linux kernel did not properly validate meta data in some circumstances. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. (CVE-2020-12655)

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)
