+permalink: /lsn/0069-1/index.html
+releases: [ubuntu-16.04-lts,ubuntu-20.04-lts,ubuntu-18.04-lts]

+description: "Several security issues were fixed in the kernel."
+---
+
+## Linux kernel vulnerabilities
+
+A security issue affects these releases of Ubuntu and its derivatives:
+
+* Ubuntu 18.04 LTS
+* Ubuntu 20.04 LTS
+* Ubuntu 16.04 LTS
+
+### Summary
+
+Several security issues were fixed in the kernel.
+
+### Software Description
+
+* linux -  Linux kernel 
+* linux-aws -  Linux kernel for Amazon Web Services (AWS) systems 
+* linux-azure -  Linux kernel for Microsoft Azure Cloud systems 
+* linux-gcp -  Linux kernel for Google Cloud Platform (GCP) systems 
+* linux-oem -  Linux kernel for OEM systems 
+
+### Details
+
+Relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local
+users to cause a denial of service (such as relay blockage) by triggering a
+NULL alloc_percpu result. (CVE-2019-19642)
+
+Fan Yang discovered that the mremap implementation in the Linux kernel did
+not properly handle DAX Huge Pages. A local attacker with access to DAX
+storage could use this to gain administrative privileges. (CVE-2020-10757)
+
+It was discovered that the DesignWare SPI controller driver in the Linux
+kernel contained a race condition. A local attacker could possibly use this
+to cause a denial of service (system crash). (CVE-2020-12769)
+
+In the Linux kernel before 5.4.16, a race condition in tty->disc_data
+handling in the slip and slcan line discipline could lead to a
+use-after-free, aka CID-0ace17d56824. This affects drivers/net/slip/slip.c
+and drivers/net/can/slcan.c. (CVE-2020-14416)
+
+## Update instructions
+
+The problem can be corrected by updating your kernel livepatch to the following
+versions:
+
+Ubuntu 18.04 LTS
+: aws - 69.1
+: generic - 69.1
+: lowlatency - 69.1
+: oem - 69.1
+
+Ubuntu 20.04 LTS
+: aws - 69.1
+: azure - 69.1
+: gcp - 69.1
+: generic - 69.1
+: lowlatency - 69.1
+
+Ubuntu 16.04 LTS
+: aws - 69.1
+: generic - 69.1
+: lowlatency - 69.1
+
