CVE-2018-12207

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.

This kernel update is based on the upstream 5.3.11 and fixes at least the following security issues:

Insufficient access control in a subsystem for Intel (R) processor graphics may allow an authenticated user to potentially enable escalation of privilege via local access (CVE-2019-0155).

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access (CVE-2019-11135).

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access (CVE-2018-12207).

For proper mitigations and fixes for theese issues, a microcode update is also needed, either with a bios/uefi update from your hardware vendor or by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688).

For other upstream fixes in this update, see the referenced changelogs.

This kernel-linus update is based on the upstream 5.3.11 and fixes at least the following security issues:

Insufficient access control in a subsystem for Intel (R) processor graphics may allow an authenticated user to potentially enable escalation of privilege via local access (CVE-2019-0155).

A Spectre SWAPGS gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel (CVE-2019-1125).

A flaw was found in the Linux kernel’s Bluetooth implementation of UART. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash (CVE-2019-10207).

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access (CVE-2019-11135).

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access (CVE-2018-12207).

For proper mitigations and fixes for theese issues, a microcode update is also needed, either with a bios/uefi update from your hardware vendor or by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688).

There is heap-based buffer overflow in the marvell wifi chip driver that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816).

An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (CVE-2019-14821).

A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host (CVE-2019-14835).

In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information from kernel stack memory because tos and flags fields are not initialized (CVE-2019-16714)

rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow (CVE-2019-17666)

For other upstream fixes in this update, see the referenced changelogs.

This update provides the Intel 20191112 microcode release that adds the microcode side fixes and mitigations for at least the following security issues:

A flaw was found in the implementation of SGX around the access control of protected memory. A local attacker of a system with SGX enabled and an affected intel GPU with the ability to execute code is able to infer the contents of the SGX protected memory (CVE-2019-0117).

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135).

Improper conditions check in the voltage modulation interface for some Intel(R) Xeon(R) Scalable Processors may allow a privileged user to potentially enable denial of service via local access (CVE-2019-11139).

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access (CVE-2018-12207).

• CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

  The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

• CVE-2019-12068: Fixed potential DOS in lsi scsi controller emulation (bsc#1146873)
• CVE-2019-11135: Expose taa-no 'feature', indicating CPU does not have the TSX Async Abort vulnerability. (bsc#1152506)
• CVE-2018-12207: Expose pschange-mc-no 'feature', indicating CPU does not have the page size change machine check vulnerability (bsc#1117665)

Other issues fixed:

• Change how this bug gets fixed (bsc#1144087)
• Disable file locking in the Xen PV disk backend to avoid locking issues with PV domUs during migration. The issues triggered by the locking can not be properly handled in libxl. The locking introduced in qemu-2.10 was removed again in qemu-4.0. (bsc#1079730, bsc#1098403, bsc#1111025, bsc#1145427, bsc#1145774)
• Feature support for vfio-ccw dasd ipl (bsc#1145379 jira-SLE-6132)
