Red Hat Security Advisory 2016-0103-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the x86 ISA is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way delivering of benign exceptions such as #DB is handled. A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel. A use-after-free flaw was found in the way the Linux kernel's key management subsystem handled keyring object reference counting in certain error path of the join_session_keyring() function. A local, unprivileged user could use this flaw to escalate their privileges on the system.

An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the host OS. It was discovered that the ppp implementation in the Linux kernel did not ensure that certain slot numbers are valid. A local attacker with the privilege to call ioctl() on /dev/ppp could cause a denial of service (system crash). Various other issues were also addressed.
