Red Hat Security Advisory 2017-2669-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab's free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation.

Security Fix: An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges.

Security Fix: It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946.
597c633d164dd5b659055724a7f94dfa6104bd1ddf58babc8fd4e61d37290908Ubuntu Security Notice 3161-3 - Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the TTY implementation in the Linux kernel. A local attacker could use this to expose sensitive information. It was discovered that the Video For Linux Two implementation in the Linux kernel did not properly handle multiple planes when processing a VIDIOC_DQBUF ioctl. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

A local attacker could use this to cause a denial of service (system crash). Dmitry Vyukov discovered a use-after-free vulnerability during error processing in the recvmmsg(2) implementation in the Linux kernel. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other kernel vulnerabilities were also discovered and addressed.
