Red Hat Security Advisory 2019-4159-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include a use-after-free vulnerability.
c4d981a6d20c3b68f13754d69107ef1f2830d0614b7c688281421d5b6b20e939Red Hat Security Advisory 2017-2931-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket could use this flaw to elevate their privileges on the system.

668de5ec7c2ffb14d70f655cc1fae90c9916874f80e9a59e8ec1cecdaf1fa43bUbuntu Security Notice 3251-2 - USN-3251-1 fixed a vulnerability in the Linux kernel for Ubuntu 16.10. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.10 for Ubuntu 16.04 LTS. It was discovered that the xfrm framework for transforming packets in the Linux kernel did not properly validate data received from user space. A local attacker could use this to cause a denial of service or execute arbitrary code with administrative privileges. Various other issues were also addressed.
