TITLE

Linux Kernel  Buffer Error Vulnerability

DESCRIPTION

An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. Linux Kernel Is vulnerable to a buffer error.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Arch Linux is an application system of Arch open source. A lightweight and flexible Linux® distribution that tries to keep it simple. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. Bug Fix(es): * Rebase package(s) to version: 1.2.23 Highlights, important fixes, or notable enhancements: * imgbase should not copy the selinux binary policy file (BZ# 1979624) (BZ#1989397) * RHV-H has been rebased on Red Hat Enterprise Linux 8.4 Batch #2. (BZ#1975177) 4. 8.2) - ppc64le, x86_64 3. Description: This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel. Description: Red Hat Advanced Cluster Management for Kubernetes 2.1.12 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.
