Details

It was discovered that a buffer overflow existed in the 802.11 Wi-Fi
configuration interface for the Linux kernel when handling beacon settings.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2019-16746)

Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel
did not properly validate SSID lengths. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2019-17133)

It was discovered that the ADIS16400 IIO IMU Driver for the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19060)

It was discovered that the Intel OPA Gen1 Infiniband Driver for the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2019-19065)

It was discovered that the Cascoda CA8210 SPI 802.15.4 wireless controller
driver for the Linux kernel did not properly deallocate memory in certain
error conditions. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2019-19075)

Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux
kernel performed DMA from a kernel stack. A local attacker could use this
to cause a denial of service (system crash). (CVE-2019-17075)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04
Ubuntu 16.04

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
