CVE-2021-22543

TITLE

Red Hat Security Advisory 2021-3943-01

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. These packages include redhat-release-virtualization-host. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. (BZ#2010171) 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.

Bug Fix(es): * [CKI kernel builds]: x86 binaries in non-x86 kernel rpms breaks systemtap [7.9.z] (BZ#1975161) 4. ========================================================================== Ubuntu Security Notice USN-5071-3 September 22, 2021 linux-raspi, linux-raspi-5.4 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-raspi: Linux kernel for Raspberry Pi (V8) systems - linux-raspi-5.4: Linux kernel for Raspberry Pi (V8) systems Details: It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. An attacker who could start and control a VM could possibly use this to expose sensitive information or execute arbitrary code. (CVE-2021-22543) Murray McAllister discovered that the joystick device interface in the Linux kernel did not properly validate data passed via an ioctl(). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code on systems with a joystick device registered. (CVE-2021-3612) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.4.0-1043-raspi 5.4.0-1043.47 linux-image-raspi 5.4.0.1043.78 linux-image-raspi2 5.4.0.1043.78 Ubuntu 18.04 LTS: linux-image-5.4.0-1043-raspi 5.4.0-1043.47~18.04.1 linux-image-raspi-hwe-18.04 5.4.0.1043.46 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
