Vulnerability from variot
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)

- ========================================================================== Ubuntu Security Notice USN-5070-1 September 08, 2021
linux, linux-aws, linux-aws-5.11, linux-azure, linux-azure-5.11, linux-gcp, linux-hwe-5.11, linux-kvm, linux-oracle, linux-oracle-5.11, linux-raspi vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel. An attacker in a guest VM could use this to read or write portions of the host's physical memory. (CVE-2021-3656)
Maxim Levitsky discovered that the KVM hypervisor implementation for AMD processors in the Linux kernel did not properly prevent a guest VM from enabling AVIC in nested guest VMs. An attacker in a guest VM could use this to write to portions of the host's physical memory. (CVE-2021-3653)
It was discovered that the Linux kernel did not properly enforce certain types of entries in the Secure Boot Forbidden Signature Database (aka dbx) protection mechanism. An attacker could use this to bypass UEFI Secure Boot restrictions. (CVE-2020-26541)
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)
Norbert Slusarek discovered that the CAN broadcast manger (bcm) protocol implementation in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-34693)
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)
It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly compute the access permissions for shadow pages in some situations. A local attacker could use this to cause a denial of service. (CVE-2021-38198)
It was discovered that the perf subsystem in the Linux kernel for the PowerPC architecture contained a null pointer dereference in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2021-38200)
Ben Greear discovered that the mac80211 subsystem in the Linux kernel contained a null pointer dereference in some situations. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2021-38206)
It was discovered that the Xilinx LL TEMAC device driver in the Linux kernel did not properly calculate the number of buffers to be used in certain situations. A remote attacker could use this to cause a denial of service (system crash). (CVE-2021-38207)

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.
Bug Fix(es):
- [CKI kernel builds]: x86 binaries in non-x86 kernel rpms breaks systemtap [7.9.z] (BZ#1975161)

An attacker in a\nguest VM could use this to read or write portions of the host\u0027s physical\nmemory. (CVE-2021-3656)\n\nMaxim Levitsky discovered that the KVM hypervisor implementation for AMD\nprocessors in the Linux kernel did not properly prevent a guest VM from\nenabling AVIC in nested guest VMs. An attacker in a guest VM could use this\nto write to portions of the host\u0027s physical memory. (CVE-2021-3653)\n\nIt was discovered that the Linux kernel did not properly enforce certain\ntypes of entries in the Secure Boot Forbidden Signature Database (aka dbx)\nprotection mechanism. An attacker could use this to bypass UEFI Secure Boot\nrestrictions. (CVE-2020-26541)\n\nIt was discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly perform reference counting in some situations,\nleading to a use-after-free vulnerability. An attacker who could start and\ncontrol a VM could possibly use this to expose sensitive information or\nexecute arbitrary code. (CVE-2021-22543)\n\nNorbert Slusarek discovered that the CAN broadcast manger (bcm) protocol\nimplementation in the Linux kernel did not properly initialize memory in\nsome situations. A local attacker could use this to expose sensitive\ninformation (kernel memory). (CVE-2021-34693)\n\nMurray McAllister discovered that the joystick device interface in the\nLinux kernel did not properly validate data passed via an ioctl(). A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code on systems with a joystick device\nregistered. (CVE-2021-3612)\n\nIt was discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly compute the access permissions for shadow pages in\nsome situations. A local attacker could use this to cause a denial of\nservice. (CVE-2021-38198)\n\nIt was discovered that the perf subsystem in the Linux kernel for the\nPowerPC architecture contained a null pointer dereference in some\nsituations. An attacker could use this to cause a denial of service (system\ncrash). (CVE-2021-38200)\n\nBen Greear discovered that the mac80211 subsystem in the Linux kernel\ncontained a null pointer dereference in some situations. A physically\nproximate attacker could possibly use this to cause a denial of service\n(system crash). (CVE-2021-38206)\n\nIt was discovered that the Xilinx LL TEMAC device driver in the Linux\nkernel did not properly calculate the number of buffers to be used in\ncertain situations. A remote attacker could use this to cause a denial of\nservice (system crash). (CVE-2021-38207)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 21.04:\n linux-image-5.11.0-1015-azure 5.11.0-1015.16\n linux-image-5.11.0-1015-kvm 5.11.0-1015.16\n linux-image-5.11.0-1017-aws 5.11.0-1017.18\n linux-image-5.11.0-1017-oracle 5.11.0-1017.18\n linux-image-5.11.0-1017-raspi 5.11.0-1017.18\n linux-image-5.11.0-1017-raspi-nolpae 5.11.0-1017.18\n linux-image-5.11.0-1018-gcp 5.11.0-1018.20\n linux-image-5.11.0-34-generic 5.11.0-34.36\n linux-image-5.11.0-34-generic-64k 5.11.0-34.36\n linux-image-5.11.0-34-generic-lpae 5.11.0-34.36\n linux-image-5.11.0-34-lowlatency 5.11.0-34.36\n linux-image-aws 5.11.0.1017.18\n linux-image-azure 5.11.0.1015.16\n linux-image-gcp 5.11.0.1018.18\n linux-image-generic 5.11.0.34.36\n linux-image-generic-64k 5.11.0.34.36\n linux-image-generic-lpae 5.11.0.34.36\n linux-image-gke 5.11.0.1018.18\n linux-image-kvm 5.11.0.1015.16\n linux-image-lowlatency 5.11.0.34.36\n linux-image-oem-20.04 5.11.0.34.36\n linux-image-oracle 5.11.0.1017.18\n linux-image-raspi 5.11.0.1017.15\n linux-image-raspi-nolpae 5.11.0.1017.15\n linux-image-virtual 5.11.0.34.36\n\nUbuntu 20.04 LTS:\n linux-image-5.11.0-1015-azure 5.11.0-1015.16~20.04.1\n linux-image-5.11.0-1017-aws 5.11.0-1017.18~20.04.1\n linux-image-5.11.0-1017-oracle 5.11.0-1017.18~20.04.1\n linux-image-5.11.0-34-generic 5.11.0-34.36~20.04.1\n linux-image-5.11.0-34-generic-64k 5.11.0-34.36~20.04.1\n linux-image-5.11.0-34-generic-lpae 5.11.0-34.36~20.04.1\n linux-image-5.11.0-34-lowlatency 5.11.0-34.36~20.04.1\n linux-image-aws 5.11.0.1017.18~20.04.16\n linux-image-generic-64k-hwe-20.04 5.11.0.34.36~20.04.13\n linux-image-generic-hwe-20.04 5.11.0.34.36~20.04.13\n linux-image-generic-lpae-hwe-20.04 5.11.0.34.36~20.04.13\n linux-image-lowlatency-hwe-20.04 5.11.0.34.36~20.04.13\n linux-image-oracle 5.11.0.1017.18~20.04.10\n linux-image-virtual-hwe-20.04 5.11.0.34.36~20.04.13\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nBug Fix(es):\n\n* [CKI kernel builds]: x86 binaries in non-x86 kernel rpms breaks systemtap\n[7.9.z] (BZ#1975161)\n\n4",
