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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

  2. 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. ========================================================================== Ubuntu Security Notice USN-5094-1 September 29, 2021

linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-dell300x, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-snapdragon vulnerabilities ==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 18.04 LTS
  • Ubuntu 16.04 ESM
  • Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in the Linux kernel. An attacker who could start and control a VM could possibly use this to expose sensitive information or execute arbitrary code. (CVE-2021-22543)

It was discovered that the tracing subsystem in the Linux kernel did not properly keep track of per-cpu ring buffer state. A privileged attacker could use this to cause a denial of service. (CVE-2021-3679)

Alois Wohlschlager discovered that the overlay file system in the Linux kernel did not restrict private clones in some situations. An attacker could use this to expose sensitive information. (CVE-2021-3732)

Alexey Kardashevskiy discovered that the KVM implementation for PowerPC systems in the Linux kernel did not properly validate RTAS arguments in some situations. An attacker in a guest vm could use this to cause a denial of service (host OS crash) or possibly execute arbitrary code. (CVE-2021-37576)

It was discovered that the MAX-3421 host USB device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-38204)

It was discovered that the Xilinx 10/100 Ethernet Lite device driver in the Linux kernel could report pointer addresses in some situations. An attacker could use this information to ease the exploitation of another vulnerability. (CVE-2021-38205)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

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

Description:\n\nThis is a kernel live patch module which is automatically loaded by the RPM\npost-install script to modify the code of a running kernel. ==========================================================================\nUbuntu Security Notice USN-5094-1\nSeptember 29, 2021\n\nlinux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15,\nlinux-dell300x, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm,\nlinux-oracle, linux-snapdragon vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 18.04 LTS\n- Ubuntu 16.04 ESM\n- Ubuntu 14.04 ESM\n\nSummary:\n\nSeveral security issues were fixed in the Linux kernel. 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\nIt was discovered that the tracing subsystem in the Linux kernel did not\nproperly keep track of per-cpu ring buffer state. A privileged attacker\ncould use this to cause a denial of service. (CVE-2021-3679)\n\nAlois Wohlschlager discovered that the overlay file system in the Linux\nkernel did not restrict private clones in some situations. An attacker\ncould use this to expose sensitive information. (CVE-2021-3732)\n\nAlexey Kardashevskiy discovered that the KVM implementation for PowerPC\nsystems in the Linux kernel did not properly validate RTAS arguments in\nsome situations. An attacker in a guest vm could use this to cause a denial\nof service (host OS crash) or possibly execute arbitrary code. \n(CVE-2021-37576)\n\nIt was discovered that the MAX-3421 host USB device driver in the Linux\nkernel did not properly handle device removal events. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2021-38204)\n\nIt was discovered that the Xilinx 10/100 Ethernet Lite device driver in the\nLinux kernel could report pointer addresses in some situations. An attacker\ncould use this information to ease the exploitation of another\nvulnerability. (CVE-2021-38205)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 18.04 LTS:\n  linux-image-4.15.0-1028-dell300x  4.15.0-1028.33\n  linux-image-4.15.0-1081-oracle  4.15.0-1081.89\n  linux-image-4.15.0-1100-kvm     4.15.0-1100.102\n  linux-image-4.15.0-1109-gcp     4.15.0-1109.123\n  linux-image-4.15.0-1112-aws     4.15.0-1112.119\n  linux-image-4.15.0-1113-snapdragon  4.15.0-1113.122\n  linux-image-4.15.0-1124-azure   4.15.0-1124.137\n  linux-image-4.15.0-159-generic  4.15.0-159.167\n  linux-image-4.15.0-159-generic-lpae  4.15.0-159.167\n  linux-image-4.15.0-159-lowlatency  4.15.0-159.167\n  linux-image-aws-lts-18.04       4.15.0.1112.115\n  linux-image-azure-lts-18.04     4.15.0.1124.97\n  linux-image-dell300x            4.15.0.1028.30\n  linux-image-gcp-lts-18.04       4.15.0.1109.128\n  linux-image-generic             4.15.0.159.148\n  linux-image-generic-lpae        4.15.0.159.148\n  linux-image-kvm                 4.15.0.1100.96\n  linux-image-lowlatency          4.15.0.159.148\n  linux-image-oracle-lts-18.04    4.15.0.1081.91\n  linux-image-snapdragon          4.15.0.1113.116\n  linux-image-virtual             4.15.0.159.148\n\nUbuntu 16.04 ESM:\n  linux-image-4.15.0-1081-oracle  4.15.0-1081.89~16.04.1\n  linux-image-4.15.0-1109-gcp     4.15.0-1109.123~16.04.1\n  linux-image-4.15.0-1112-aws     4.15.0-1112.119~16.04.1\n  linux-image-4.15.0-1124-azure   4.15.0-1124.137~16.04.1\n  linux-image-4.15.0-159-generic  4.15.0-159.167~16.04.1\n  linux-image-4.15.0-159-lowlatency  4.15.0-159.167~16.04.1\n  linux-image-aws-hwe             4.15.0.1112.103\n  linux-image-azure               4.15.0.1124.115\n  linux-image-gcp                 4.15.0.1109.110\n  linux-image-generic-hwe-16.04   4.15.0.159.152\n  linux-image-gke                 4.15.0.1109.110\n  linux-image-lowlatency-hwe-16.04  4.15.0.159.152\n  linux-image-oem                 4.15.0.159.152\n  linux-image-oracle              4.15.0.1081.69\n  linux-image-virtual-hwe-16.04   4.15.0.159.152\n\nUbuntu 14.04 ESM:\n  linux-image-4.15.0-1124-azure   4.15.0-1124.137~14.04.1\n  linux-image-azure               4.15.0.1124.97\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",
