Ubuntu Security Notice USN-6820-1
June 07, 2024

linux, linux-gcp, linux-gcp-5.15, linux-lowlatency,
linux-lowlatency-hwe-5.15, linux-xilinx-zynqmp vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-lowlatency: Linux low latency kernel
- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-lowlatency-hwe-5.15: Linux low latency kernel

Details:

It was discovered that the ATA over Ethernet (AoE) driver in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the Atheros 802.11ac wireless driver did not
properly validate certain data structures, leading to a NULL pointer
dereference. An attacker could possibly use this to cause a denial of
service. (CVE-2023-7042)

It was discovered that the HugeTLB file system component of the Linux
Kernel contained a NULL pointer dereference vulnerability. A privileged
attacker could possibly use this to to cause a denial of service.
(CVE-2024-0841)

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)

Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux
Kernel contained a race condition, leading to a NULL pointer dereference.
An attacker could possibly use this to cause a denial of service (system
crash). (CVE-2024-22099)

It was discovered that the MediaTek SoC Gigabit Ethernet driver in the
Linux kernel contained a race condition when stopping the device. A local
attacker could possibly use this to cause a denial of service (device
unavailability). (CVE-2024-27432)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

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.
