vulnerability existed in the AF_UNIX implementation in the Linux kernel.
A local attacker could use crafted epoll_ctl calls to cause a denial of
service (system crash) or expose sensitive information. (CVE-2013-7446)
It was discovered that the KVM implementation in the Linux kernel did not
properly restore the values of the Programmable Interrupt Timer (PIT). A
user-assisted attacker in a KVM guest could cause a denial of service in
the host (system crash). (CVE-2015-7513)
Sasha Levin discovered that the Reliable Datagram Sockets (RDS)
implementation in the Linux kernel had a race condition when checking
whether a socket was bound or not. A local attacker could use this to cause
a denial of service (system crash). (CVE-2015-7990)
It was discovered that the Btrfs implementation in the Linux kernel
incorrectly handled compressed inline extants on truncation. A local
attacker could use this to expose sensitive information. (CVE-2015-8374)
It was discovered that the netfilter Network Address Translation (NAT)
implementation did not ensure that data structures were initialized when
handling IPv4 addresses. An attacker could use this to cause a denial of
service (system crash). (CVE-2015-8787)");
