Summary
linux, linux-aws, linux-aws-hwe, linux-azure, linux-hwe, linux-kvm, linux-oem, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities
Details

It was discovered that the XFS file system in the Linux kernel did not properly handle mount failures in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-20976)

Benjamin Moody discovered that the XFS file system in the Linux kernel did not properly handle an error condition when out of disk quota. A local attacker could possibly use this to cause a denial of service. (CVE-2019-15538)
