Insufficient access control in a subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900 Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families; Intel(R) Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077 (aka15.45.5077), i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an authenticated user to potentially enable escalation of privilege 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.

The openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2019-0154: An unprotected read access to i915 registers has been fixed that could have been abused to facilitate a local denial-of-service attack. (bsc#1135966)

• CVE-2019-0155: A privilege escalation vulnerability has been fixed in the i915 module that allowed batch buffers from user mode to gain super user privileges. (bsc#1135967)

• CVE-2019-16231: drivers/net/fjes/fjes_main.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference (bnc#1150466).

• CVE-2019-18805: There was a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6 (bnc#1156187).

• CVE-2019-17055: base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module did not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21 (bnc#1152782).

• CVE-2019-16995: A memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c, if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d (bnc#1152685).

• 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).

  The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251

• CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference (bnc#1150457).

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

  The Linux Kernel kvm hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735

• CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).

• 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).
