CVE-2022-1679 An use-after-free flaw was found in the Atheros wireless adapter driver, which could lead to remote code execution.

CVE-2022-1679 An use-after-free flaw was found in the Atheros wireless adapter driver, which could lead to remote code execution.

This issue affects all Linux kernel versions and will likely be fixed in a future version of the operating system.
In addition, this update fixes the following issue: - Previously, in some situations an attacker could create a malicious Wireless Network connection to force an application to crash, making it possible to execute arbitrary code with root privileges.
With this update, Linux can now detect when an attacker tries to create a malicious Wireless Network connection, and the user will be notified about the possible danger to prevent such an attack. Last year in September, Google released the patch for the use-after-free flaw in the Linux kernel.
In addition, this update fixes the following issue: - Previously, when using the perf tool to analyze a process that used the Linux kernel’sring_buffer_operations functionality, users could see a performance penalty on systems with a large number of CPUs. Now, with this update, perf will no longer show a performance penalty on systems with a large number of CPUs. And this update fixes an issue where perf would return incorrect CPU usage information for processes that used thering_buffer_operations functionality. - Previously, when using the 'perf record' tool, users could see an incorrect stack trace when trying to run a process that used thering_buffer_operations functionality. With this update, perf will no longer show an incorrect stack trace when running a process that uses thering_buffer_operations functionality

The Linux kernel is an open-source core component of many modern operating systems, including:

CentOS, Fedora, Gentoo, Debian and Ubuntu.
- The Linux kernel is normally used in conjunction with a bootloader to load an operating system kernel that has been installed on the computer.
- It provides application programming interfaces (API) for device drivers and system programmers to develop software that can interact with hardware components of the computer.
- The Linux kernel also includes support for many device drivers, file systems and network protocols.
- The Linux kernel is maintained by developers from around the world who have contributed their time and effort to help make it more robust and reliable than any other operating system currently available.

How to Install this Update?

First, run the following command to download the linux-4.10.0-1402-x86_64 package:

wget http://download.savannah.gnu.org/releases/linux/4.10.0/x86_64/linux-4.10.0-1402-x86_64.tar.gz
Then, run the following command to install the linux-4.10.0-1402-x86_64 package:
sudo tar -C / -xzpf linux-4.10.0-1402-x86_64*.tar.* && sudo cp -R * /usr && rm *.tar.*

Installation Instructions

This update is available from the Red Hat Network. The package name of this update is kernel-2.6.32-754.
The latest version of Red Hat Enterprise Linux includes the following packages by default: - perf -perf -perf-debuginfo -kernel-headers
Users must install these packages to use the 'perf record' tool, in order to get correct stack trace information for processes that use the ring_buffer_operations functionality.
To install this update, users must log in as root, create a temporary file to perform an rpm command and enter one line at a time, which would be "yum --enablerepo=RHEL-testing installs kernel-2.6.32-754."

What is the Linux kernel?

One of the most popular operating systems for computers today is Linux. The Linux kernel is a core component of the Unix-like operating systems that are used by many devices, like smartphones, tablets, PCs, and more.
The Linux kernel manages hardware resources on a computer and provides services like file systems and network interfaces to applications. The kernel also provides an interface between userspace and the hardware components that make up the system.
