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.

On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code with administrative privileges. It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
