A number of significant vulnerabilities addressed in Ubuntu 22.04 LTS via Ubuntu Security Notice USN-6609-2, impacting the linux-nvidia package.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-nvidia: Linux kernel for NVIDIA systems

Details:

Lin Ma discovered that the netfilter subsystem in the Linux kernel did not

properly validate network family support while creating a new netfilter

table. A local attacker could use this to cause a denial of service or

possibly execute arbitrary code. (CVE-2023-6040)

It was discovered that the CIFS network file system implementation in the

Linux kernel did not properly validate the server frame size in certain

situation, leading to an out-of-bounds read vulnerability. An attacker

could use this to construct a malicious CIFS image that, when operated on,

could cause a denial of service (system crash) or possibly expose sensitive

information. (CVE-2023-6606)

Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did

not properly handle inactive elements in its PIPAPO data structure, leading

to a use-after-fre...

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-5.15.0-1043-nvidia  5.15.0-1043.43
   linux-image-5.15.0-1043-nvidia-lowlatency  5.15.0-1043.43
   linux-image-nvidia              5.15.0.1043.43
   linux-image-nvidia-lowlatency   5.15.0.1043.43

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.
