USN-3878-1: Linux kernel vulnerabilities
USN-3878-1: Linux kernel vulnerabilities linux, linux-aws, linux-gcp, linux-kvm, linux-raspi2 vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 18.10 Summary Several security issues were fixed in the Linux kernel. Software Description linux – Linux kernel linux-aws – Linux kernel for Amazon Web Services (AWS) systems linux-gcp – Linux kernel for Google Cloud Platform (GCP) systems linux-kvm – Linux kernel for cloud environments linux-raspi2 – Linux kernel for Raspberry Pi 2 Details It was discovered that a race condition existed in the vsock address family implementation of the Linux kernel that could lead to a use-after-free condition. A local attacker in a guest virtual machine could use this to expose sensitive information (host machine kernel memory). (CVE-2018-14625) Cfir Cohen discovered that a use-after-free vulnerability existed in the KVM implementation of the Linux kernel, when handling interrupts in [ more… ]
