An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by the functions gfs2_clear_rgrpd and read_rindex_entry.

Affected: Ubuntu:16.04:LTS: linux, Ubuntu:16.04:LTS: linux-aws, Ubuntu:16.04:LTS: linux-kvm, Ubuntu:16.04:LTS: linux-raspi2, Ubuntu:16.04:LTS: linux-snapdragon

It 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). (CVE-2016-10905)

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 (system crash) or possibly execute arbitrary code. (CVE-2017-18509)

It was discovered that the USB gadget Midi driver in the Linux kernel contained a double-free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-20961)

It was discovered that the XFS file system in the Linux kernel did not properly handle mount failures in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-20976)

It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136)

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. (CVE-2019-10207)

It was discovered that an integer overflow existed in the Linux kernel when reference…
