Ubuntu 22.04 LTS: USN-6057-1 Moderate Kernel Advisory on Intel IoT

ubuntu
Calendar Grey May 5, 2023
Dist Ubuntu Esm H88
Ubuntu tackles major kernel flaws impacting Intel IoT, implementing essential updates to ensure system safety.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-intel-iotg: Linux kernel for Intel IoT platforms

Details:

It was discovered that the Traffic-Control Index (TCINDEX) implementation

in the Linux kernel contained a use-after-free vulnerability. A local

attacker could use this to cause a denial of service (system crash) or

possibly execute arbitrary code. (CVE-2023-1281)

It was discovered that the OverlayFS implementation in the Linux kernel did

not properly handle copy up operation in some conditions. A local attacker

could possibly use this to gain elevated privileges. (CVE-2023-0386)

Haowei Yan discovered that a race condition existed in the Layer 2

Tunneling Protocol (L2TP) implementation in the Linux kernel. A local

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

crash). (CVE-2022-4129)

It was discovered that the network queuing discipline implementation in the

Linux kernel contained a null po...

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-5.15.0-1028-intel-iotg  5.15.0-1028.33
   linux-image-intel-iotg          5.15.0.1028.27

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.
