USN-4145-1: Linux kernel vulnerabilities<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
It was discovered that a race condition existed in the GFS2 file system in
\nthe Linux kernel. A local attacker could possibly use this to cause a
\ndenial of service (system crash). (CVE-2016-10905)<\/p>\n
It was discovered that the IPv6 implementation in the Linux kernel did not
\nproperly validate socket options in some situations. A local attacker could
\nuse this to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2017-18509)<\/p>\n
It was discovered that the USB gadget Midi driver in the Linux kernel
\ncontained a double-free vulnerability when handling certain error
\nconditions. A local attacker could use this to cause a denial of service
\n(system crash). (CVE-2018-20961)<\/p>\n
It was discovered that the XFS file system in the Linux kernel did not
\nproperly handle mount failures in some situations. A local attacker could
\npossibly use this to cause a denial of service (system crash) or execute
\narbitrary code. (CVE-2018-20976)<\/p>\n
It was discovered that the Intel Wi-Fi device driver in the Linux kernel
\ndid not properly validate certain Tunneled Direct Link Setup (TDLS). A
\nphysically proximate attacker could use this to cause a denial of service
\n(Wi-Fi disconnect). (CVE-2019-0136)<\/p>\n
It was discovered that the Bluetooth UART implementation in the Linux
\nkernel did not properly check for missing tty operations. A local attacker
\ncould use this to cause a denial of service. (CVE-2019-10207)<\/p>\n
It was discovered that an integer overflow existed in the Linux kernel when
\nreference counting pages, leading to potential use-after-free issues. A
\nlocal attacker could use this to cause a denial of service (system crash)
\nor possibly execute arbitrary code. (CVE-2019-11487)<\/p>\n
It was discovered that the GTCO tablet input driver in the Linux kernel did
\nnot properly bounds check the initial HID report sent by the device. A
\nphysically proximate attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2019-13631)<\/p>\n
It was discovered that the Raremono AM\/FM\/SW radio device driver in the
\nLinux kernel did not properly allocate memory, leading to a use-after-free.
\nA physically proximate attacker could use this to cause a denial of service
\nor possibly execute arbitrary code. (CVE-2019-15211)<\/p>\n
It was discovered that a race condition existed in the CPiA2 video4linux
\ndevice driver for the Linux kernel, leading to a use-after-free. A
\nphysically proximate attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2019-15215)<\/p>\n
It was discovered that the Atheros mobile chipset driver in the Linux
\nkernel did not properly validate data in some situations. An attacker could
\nuse this to cause a denial of service (system crash). (CVE-2019-15926)<\/p>\n
The problem can be corrected by updating your system to the following package versions:<\/p>\n
To update your system, please follow these instructions: https:\/\/wiki.ubuntu.com\/Security\/Upgrades<\/a>.<\/p>\n After a standard system update you need to reboot your computer to make ATTENTION: Due to an unavoidable ABI change the kernel updates have Source: USN-4145-1: Linux kernel vulnerabilities<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" USN-4145-1: Linux kernel vulnerabilities linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 16.04 LTS Summary Several security issues were fixed in the Linux kernel.

\nall the necessary changes.<\/p>\n
\nbeen given a new version number, which requires you to recompile and
\nreinstall all third party kernel modules you might have installed.
\nUnless you manually uninstalled the standard kernel metapackages
\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
\nlinux-powerpc), a standard system upgrade will automatically perform
\nthis as well.<\/p>\nReferences<\/h2>\n
