Ubuntu Security Notice 2337-1 - A flaw was discovered in the Linux kernel virtual machine's (kvm) validation of interrupt requests (irq). A guest OS user could exploit this flaw to cause a denial of service (host OS crash). Andy Lutomirski discovered a flaw in the authorization of netlink socket operations when a socket is passed to a process of more privilege. A local user could exploit this flaw to bypass access restrictions by having a privileged executable do something it was not intended to do. Various other issues were also addressed.
