Vulnerability from variot
An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. Linux Kernel There is an authentication vulnerability in.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Attackers can use this vulnerability to bypass the restrictions of the Linux kernel through Cgroup Fd Writing to elevate their privileges. ========================================================================== Ubuntu Security Notice USN-5368-1 April 06, 2022

A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-27666)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: linux-image-5.13.0-1021-azure 5.13.0-1021.24~20.04.1 linux-image-5.13.0-1025-oracle 5.13.0-1025.30~20.04.1 linux-image-azure 5.13.0.1021.24~20.04.10 linux-image-oracle 5.13.0.1025.30~20.04.1
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.
