The kvm_apic_has_events function in arch/x86/kvm/lapic.h in the Linux kernel through 4.1.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging /dev/kvm access for an ioctl call.

Affected: Ubuntu:14.04:LTS: linux

A flaw was discovered in the user space memory copying for the pipe iovecs in the Linux kernel. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges. (CVE-2015-1805)

A flaw was discovered in the kvm (kernel virtual machine) subsystem's kvm_apic_has_events function. A unprivileged local user could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4692)

Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter JIT optimization. A local attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4700)

A flaw was discovered in how the Linux kernel handles invalid UDP checksums. A remote attacker could exploit this flaw to cause a denial of service using a flood of UDP packets with invalid checksums. (CVE-2015-5364)

A flaw was discovered in how the Linux kernel handles invalid UDP checksums. A remote attacker can cause a denial of service against applications that use epoll by injecting a single packet with an invalid checksum. (CVE-2015-5366)

A double free flaw was discovered in the Linux kernel's path lookup. A local user could cause a denial of service (Oops). (CVE-2015-5706)
