59cc375374ff6c15113d1988a4247e3d24bd10d07e2610dd9344468468bbc9e6It was discovered that a race condition existed in the GFS2 file system in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.
5442de6a129171e9103a7acd9d861ab0fda6074505e32a4ad08db9df45b30c61Ubuntu Security Notice 4147-1 - It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup. A physically proximate attacker could use this to cause a denial of service. It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

A local attacker could possibly use this to cause a denial of service. It was discovered that the IPv6 implementation in the Linux kernel did not properly validate socket options in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
d8ef831cccbb75205a0fe90a3bdbf104e78019136be3165a75d091b11d684f97Ubuntu Security Notice 4115-2 - USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update, a regression was introduced that caused a kernel crash when handling fragmented packets in some situations. This update addresses the issue. Various other issues were also addressed.

A local attacker could use this to cause a denial of service. Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track inode validations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. Various other issues were also addressed.
4f908bb81d9ebb9dd129fad885aa16a8ad89f97c5c09adc998aefff895ea8268Ubuntu Security Notice 4115-1 - Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service. Zhipeng Xie discovered that an infinite loop could triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.
