TITLE

Linux Kernel  Authentication vulnerability in

DESCRIPTION

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. Description: Red Hat Advanced Cluster Management for Kubernetes 2.4.5 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in.

Software Description: - linux-kvm: Linux kernel for cloud environments - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of the Linux kernel leading to multiple use-after-free vulnerabilities. A local attacker could use this issue to execute arbitrary code. (CVE-2021-3609) Likang Luo discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-3752) It was discovered that the NFC subsystem in the Linux kernel contained a use-after-free vulnerability in its NFC Controller Interface (NCI) implementation. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3760) Szymon Heidrich discovered that the USB Gadget subsystem in the Linux kernel did not properly restrict the size of control requests for certain gadget types, leading to possible out of bounds reads or writes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-39685) It was discovered that the Ion Memory Manager subsystem in the Linux kernel contained a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-39714) Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. (CVE-2021-4197) Lin Ma discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4202) Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in the Linux kernel did not perform a GPU TLB flush in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-0330) It was discovered that the PF_KEYv2 implementation in the Linux kernel did not properly initialize kernel memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-1353) It was discovered that the virtual graphics memory manager implementation in the Linux kernel was subject to a race condition, potentially leading to an information leak. (CVE-2022-1419) Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1652) It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1679) It was discovered that the Marvell NFC device driver implementation in the Linux kernel did not properly perform memory cleanup operations in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system) or execute arbitrary code. (CVE-2022-1734) It was discovered that some Intel processors did not completely perform cleanup actions on multi-core shared buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123) It was discovered that some Intel processors did not completely perform cleanup actions on microarchitectural fill buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21125) It was discovered that some Intel processors did not properly perform cleanup during specific special register write operations. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21166) It was discovered that the USB Gadget file system interface in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-24958) 赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not properly perform reference counting in some error conditions. (CVE-2022-28356) It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. (CVE-2022-28388) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1110-kvm 4.4.0-1110.120 linux-image-kvm 4.4.0.1110.107 Ubuntu 14.04 ESM: linux-image-4.4.0-229-generic 4.4.0-229.263~14.04.1 linux-image-4.4.0-229-lowlatency 4.4.0-229.263~14.04.1 linux-image-generic-lts-xenial 4.4.0.229.199 linux-image-lowlatency-lts-xenial 4.4.0.229.199 linux-image-virtual-lts-xenial 4.4.0.229.199 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.
