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)");
