Ubuntu 22.04 LTS USN-6466-1: Multiple Denial Of Service Issues Identified

ubuntu
Calendar Grey October 31, 2023
Dist Ubuntu Esm H88
Multiple security issues fixed in Ubuntu 22.04 LTS for the Linux kernel affecting NVIDIA systems.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-nvidia-6.2: Linux kernel for NVIDIA systems

Details:

Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel

contained a race condition during device removal, leading to a use-after-

free vulnerability. A physically proximate attacker could use this to cause

a denial of service (system crash) or possibly execute arbitrary code.

(CVE-2022-45886, CVE-2022-45919)

Hyunwoo Kim discovered that the Technotrend/Hauppauge USB DEC driver in the

Linux kernel did not properly handle device removal events. A physically

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

crash). (CVE-2022-45887)

It was discovered that the NTFS file system implementation in the Linux

kernel did not properly validate MFT flags in certain situations. An

attacker could use this to construct a malicious NTFS image that, when

mounted and operated on, could cause a denial of se...

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-6.2.0-1011-nvidia   6.2.0-1011.11
   linux-image-6.2.0-1011-nvidia-64k  6.2.0-1011.11
   linux-image-nvidia-6.2          6.2.0.1011.13
   linux-image-nvidia-64k-6.2      6.2.0.1011.13
   linux-image-nvidia-64k-hwe-22.04  6.2.0.1011.13
   linux-image-nvidia-hwe-22.04    6.2.0.1011.13

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.
