Ubuntu Security Notice 3931-2 - USN-3931-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS and for the Linux Azure kernel for Ubuntu 14.04 LTS. M. Vefa Bicakci and Andy Lutomirski discovered that the kernel did not properly set up all arguments to an error handler callback used when running as a paravirtualized guest. An unprivileged attacker in a paravirtualized guest VM could use this to cause a denial of service. Various other issues were also addressed.

An unprivileged attacker in a paravirtualized guest VM could use this to cause a denial of service. It was discovered that the KVM implementation in the Linux kernel on ARM 64bit processors did not properly handle some ioctls. An attacker with the privilege to create KVM-based virtual machines could use this to cause a denial of service or execute arbitrary code in the host. Various other issues were also addressed.

Ubuntu Security Notice 3879-1 - Wen Xu discovered that the ext4 file system implementation in the Linux kernel could possibly perform an out of bounds write when updating the journal for an inline file. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service. Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem of the Linux kernel did not properly initialize new files in some situations. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
