Summary
linux, linux-azure-4.15, linux-dell300x, linux-gcp-4.15, linux-kvm, linux-snapdragon vulnerability
Details

It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
