Ubuntu Security Notice USN-6820-1
Posted Jun 10, 2024
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 6820-1 - It was discovered that the ATA over Ethernet 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. 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.

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


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


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.

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.

Update instructions:

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

Ubuntu 22.04 LTS
linux-image-5.15.0-1030-xilinx-zynqmp 5.15.0-1030.34
linux-image-5.15.0-1062-gcp 5.15.0-1062.70
linux-image-5.15.0-110-lowlatency 5.15.0-110.120
linux-image-5.15.0-110-lowlatency-64k 5.15.0-110.120
linux-image-5.15.0-112-generic 5.15.0-112.122
linux-image-5.15.0-112-generic-64k 5.15.0-112.122
linux-image-5.15.0-112-generic-lpae 5.15.0-112.122

Ubuntu 20.04 LTS
linux-image-5.15.0-1062-gcp 5.15.0-1062.70~20.04.1
linux-image-5.15.0-110-lowlatency 5.15.0-110.120~20.04.1
linux-image-5.15.0-110-lowlatency-64k 5.15.0-110.120~20.04.1

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.
