Ubuntu Security Advisory USN-6819-3 outlines various kernel security patches for Ubuntu 23.10. Urgent update recommended without delay.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-laptop: Linux kernel for Lenovo X13s ARM laptops

Details:

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel

did not properly validate H2C PDU data, leading to a null pointer

dereference vulnerability. A remote attacker could use this to cause a

denial of service (system crash). (CVE-2023-6356, CVE-2023-6535,

CVE-2023-6536)

It was discovered that the Intel Data Streaming and Intel Analytics

Accelerator drivers in the Linux kernel allowed direct access to the

devices for unprivileged users and virtual machines. A local attacker could

use this to cause a denial of service. (CVE-2024-21823)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux

kernel contained an out-of-bounds read vulnerability. An attacker could use

this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condit...

security advisory denial of service kernel update Ubuntu system fix linux-laptop

Update Instructions

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

Ubuntu 23.10
   linux-image-6.5.0-1017-laptop   6.5.0-1017.20
   linux-image-laptop-23.10        6.5.0.1017.20

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.
