Red Hat Security Advisory 2016-2584-02 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service via a crafted sendmsg system call.

a58b7b5d58e92d5a084026c53f5461e431441e86891787922c799b50ae4376edRed Hat Security Advisory 2016-0855-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: It was found that reporting emulation failures to user space could lead to either a local or a L2->L1 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso and thus an unprivileged user may generate MMIO transactions this way.

A local attacker could use this to cause a denial of service. Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in the Linux kernel did not properly sanity check the endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash). Various other issues were also addressed.
