USN-4369-1 linux, linux-aws, linux-aws-5.3, linux-azure, linux-azure-5.3, linux-gcp, linux-gcp-5.3, linux-gke-5.3, linux-hwe, linux-kvm, linux-oracle, linux-oracle-5.3, linux-raspi2 vulnerabilities

It was discovered that the btrfs implementation in the Linux kernel did not properly detect that a block was marked dirty in some situations. An attacker could use this to specially craft a file system image that, when unmounted, could cause a denial of service system crash. CVE-2019-19377 Trista...
