USN-4228-1: Linux kernel vulnerabilities
7 January 2020
Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux - Linux kernel
- linux-aws - Linux kernel for Amazon Web Services (AWS) systems
- linux-kvm - Linux kernel for cloud environments
- linux-raspi2 - Linux kernel for Raspberry Pi 2
- linux-snapdragon - Linux kernel for Snapdragon processors
Details
It was discovered that a heap-based buffer overflow existed in the Marvell
WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-14895, CVE-2019-14901)
It was discovered that a heap-based buffer overflow existed in the Marvell
Libertas WLAN Driver for the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-14896, CVE-2019-14897)
Anthony Steinhauser discovered that the Linux kernel did not properly
perform Spectre_RSB mitigations to all processors for PowerPC architecture
systems in some situations. A local attacker could use this to expose
sensitive information. (CVE-2019-18660)
It was discovered that Geschwister Schneider USB CAN interface driver in
the Linux kernel did not properly deallocate memory in certain failure
conditions. A physically proximate attacker could use this to cause a
denial of service (kernel memory exhaustion). (CVE-2019-19052)
It was discovered that the driver for memoryless force-feedback input
devices in the Linux kernel contained a use-after-free vulnerability. A
physically proximate attacker could possibly use this to cause a denial of
service (system crash) or execute arbitrary code. (CVE-2019-19524)
It was discovered that the PEAK-System Technik USB driver in the Linux
kernel did not properly sanitize memory before sending it to the device. A
physically proximate attacker could use this to expose sensitive
information (kernel memory). (CVE-2019-19534)

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.
