Details

It was discovered that the Linux kernel did not check if a new IPv6 MTU set
by a user space application was valid. A remote attacker could forge a
route advertisement with an invalid MTU that a user space daemon like
NetworkManager would honor and apply to the kernel, causing a denial of
service. (CVE-2015-0272)

It was discovered that virtio networking in the Linux kernel did not handle
fragments correctly, leading to kernel memory corruption. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute code with administrative privileges. (CVE-2015-5156)

It was discovered that the Reliable Datagram Sockets (RDS) implementation
in the Linux kernel did not verify sockets were properly bound before
attempting to send a message, which could cause a NULL pointer dereference.
An attacker could use this to cause a denial of service (system crash).
(CVE-2015-6937)

Ben Hutchings discovered that the Advanced Union Filesystem (aufs) for the
Linux kernel did not correctly handle references of memory mapped files
from an aufs mount. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code with
administrative privileges. (CVE-2015-7312)
