CVE-2021-22543

TITLE

KVM 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. Arch Linux is an application system of Arch open source. A lightweight and flexible Linux® distribution that tries to keep it simple. 7.6) - 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: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Bug Fix(es): * Indefinite waiting for RCU callback while removing cgroup (BZ#1967844) * kernel-rt: update to the latest RHEL7.9.z9 source tree (BZ#2002994) 4. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2021:3801-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:3801 Issue date: 2021-10-12 CVE Names: CVE-2021-3653 CVE-2021-3656 CVE-2021-22543 CVE-2021-37576 ===================================================================== 1.
