Red Hat Security Advisory 2017-0817-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. 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.
597c633d164dd5b659055724a7f94dfa6104bd1ddf58babc8fd4e61d37290908Philip Pettersson discovered a race condition in the af_packet implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service (system crash) or run arbitrary code with administrative privileges. Pengfei Wang discovered a race condition in the Adaptec AAC RAID controller driver in the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system crash). Marco Grassi discovered a use-after-free condition could occur in the TCP retransmit queue handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
d8c13d40032210a719f70376fb50f745ce27eca4d0eb24c5096aaa2ba0e42b44Red 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.
