Releases

  • Ubuntu 18.04 ESM

Packages

  • linux-aws-5.3 - Linux kernel for Amazon Web Services (AWS) systems
  • linux-gke-5.3 - Linux kernel for Google Container Engine (GKE) systems
  • linux-hwe - Linux hardware enablement (HWE) kernel
  • linux-raspi2-5.3 - Linux kernel for Raspberry Pi (V8) systems

Details

It was discovered that the cgroup v2 subsystem in the Linux kernel did not
properly perform reference counting in some situations, leading to a NULL
pointer dereference. A local attacker could use this to cause a denial of
service or possibly gain administrative privileges.
