Ubuntu 20.04 LTS USN-6896-5 Moderate: Linux Kernel Denial of Service

ubuntu
Calendar Grey July 23, 2024
Dist Ubuntu Esm H88
Multiple vulnerabilities addressed in the Ubuntu kernel patch USN-6897-6 impacting AWS and IoT systems. Ensure your system is updated!
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-iot: Linux kernel for IoT platforms

- linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems

Details:

It was discovered that the ATA over Ethernet (AoE) driver in the Linux

kernel contained a race condition, leading to a use-after-free

vulnerability. An attacker could use this to cause a denial of service or

possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the Atheros 802.11ac wireless driver did not

properly validate certain data structures, leading to a NULL pointer

dereference. An attacker could possibly use this to cause a denial of

service. (CVE-2023-7042)

Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux

Kernel contained a race condition, leading to a NULL pointer dereference.

An attacker could possibly use this to cause a denial of service (system

crash). (CVE-202...

Update Instructions

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

Ubuntu 20.04 LTS
  linux-image-5.4.0-1040-iot      5.4.0-1040.41
  linux-image-5.4.0-1128-aws      5.4.0-1128.138
  linux-image-aws-lts-20.04       5.4.0.1128.125

Ubuntu 18.04 LTS
  linux-image-5.4.0-1128-aws      5.4.0-1128.138~18.04.1
                                  Available with Ubuntu Pro
  linux-image-aws                 5.4.0.1128.138~18.04.1
                                  Available with Ubuntu Pro

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.
