Ubuntu 22.04 LTS USN-6207-1 Moderate: Intel IoT Kernel DoS

ubuntu
Calendar Grey July 6, 2023
Dist Ubuntu Esm H88
Uncover vital security patches for the Linux kernel in Ubuntu relevant to Intel IoT devices to counter significant vulnerabilities.
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

- linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms

Details:

It was discovered that the TUN/TAP driver in the Linux kernel did not

properly initialize socket data. A local attacker could use this to cause a

denial of service (system crash). (CVE-2023-1076)

It was discovered that the Real-Time Scheduling Class implementation in the

Linux kernel contained a type confusion vulnerability in some situations. A

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

(CVE-2023-1077)

It was discovered that the ASUS HID driver in the Linux kernel did not

properly handle device removal, leading to a use-after-free vulnerability.

A local attacker with physical access could plug in a specially crafted USB

device to cause a denial of service (system crash). (CVE-2023-1079)

It was discovered that the Xirco...

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-5.15.0-1033-intel-iotg  5.15.0-1033.38
   linux-image-intel-iotg          5.15.0.1033.32

Ubuntu 20.04 LTS:
   linux-image-5.15.0-1033-intel-iotg  5.15.0-1033.38~20.04.1
   linux-image-intel               5.15.0.1033.38~20.04.24
   linux-image-intel-iotg          5.15.0.1033.38~20.04.24

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.
