On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION
* CVE-2015-7872: Denial-of-service when garbage collecting uninstantiated keyring.
A logic error in the security keyring subsystem leads to a kernel crash
when garbage collecting a un-instantiated keyring. A local, un-privileged
user can use this flaw to cause a denial-of-service.
* CVE-2015-7833: Denial-of-service when probing USBvision device.
Incorrect input validation when probing a USBvision device could lead to
out of bounds memory accesses and kernel panic. A local attacker with
physical access could use a fake USB device with handcrafted USB descriptor
to cause a denial-of-service.
* CVE-2015-7990: Race condition when sending a message on unbound RDS socket.
Incorrect locking when checking the state of a socket before sending a
message could lead to a NULL pointer dereference. A local, un-privileged
user could use this flaw to cause a denial-of-service.
* CVE-2015-5307: KVM host denial-of-service in alignment check.
A guest could cause a denial-of-service on a KVM host by triggering an
infinite stream of alignment check exceptions and causing the processor
microcode to enter an infinite loop. A privileged user in a guest could
use this flaw to crash the host.
