Canonical Patches Multiple Linux Kernel Vulnerabilities in Ubuntu 15.04 and 14.04 LTS

Four Linux kernel vulnerabilities were patched in Ubuntu 15.04 (Vivid Vervet) and five in Ubuntu 14.04 LTS (Trusty Tahr). The common ones are a flaw discovered in Linux kernel’s Kernel Virtual Machine (KVM)’s kvm_apic_has_events function, as well as an issue in the JIT optimization of Linux kernel’s Berkeley Packet Filter, both of which allowing a local attacker to crash the system by causing a denial of service.
