Several security issues were fixed in the kernel. Andrey Konovalov discovered that the AF_PACKET implementation in the Linux kernel did not properly validate certain block-size data. A local attacker could use this to cause a denial of service (system crash). Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. Various other issues were also addressed.
42b1d7e92d487c05901f19f08b2e6c9e119556985c2054e46a019c3a3bd7bf0dRed Hat Security Advisory 2017-0307-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.

A remote attacker could use this to cause a denial of service. It was discovered that multiple memory leaks existed in the XFS implementation in the Linux kernel. A local attacker could use this to cause a denial of service.

77d8c001f6e36a31c7d9b132fd230b09dd8d1ff369953d1af091527660b20e23Red Hat Security Advisory 2017-0113-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. The kernel-rt packages have been upgraded to version 3.10.0-514, which provides a number of security and bug fixes over the previous version. Security Fix: A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.

A local attacker could use this to cause a denial of service. Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges. Various other issues were also addressed.
