New Debian 10 Buster Linux Kernel Security Update Fixes 5 Vulnerabilities

The new Linux kernel security update patches a flaw (CVE-2020-2732) discovered by Paulo Bonzini in the KVM (Kernel-based Virtual Machine) implementation for Intel CPUs, which could allow an L2 guest to cause a denial of service, leak sensitive information from the L1 guest or escalate his/her privileges. The kernel update also fixes a vulnerability (CVE-2020-10942) discovered in Linux kernel’s vhost_net driver, which could allow a local attacker with access to /dev/vhost-net to cause a stack corruption by crafting system calls. This could lead to a denial of service (system crash) and even to privilege escalation.
