Ubuntu Security Notice USN-3698-2
Posted Jul 3, 2018
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3698-2 - USN-3698-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 ESM. It was discovered that the nested KVM implementation in the Linux kernel in some situations did not properly prevent second level guests from reading and writing the hardware CR8 register. A local attacker in a guest could use this to cause a denial of service. Various other issues were also addressed.

Linux Kernel _sctp_make_chunk() Denial Of Service
Posted Mar 1, 2018
Authored by Jakub Jirasek | Site secunia.com

Secunia Research has discovered a vulnerability in Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service). An error in the "_sctp_make_chunk()" function (net/sctp/sm_make_chunk.c) when handling SCTP packets length can be exploited to cause a kernel crash. The vulnerability is confirmed in versions 4.15.0-r7 and 4.15.0. Other versions may also be affected.
