CVE-2019-14835

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, 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.

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, 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.

This kernel update is based on the upstream 4.14.145 and fixes at least the following security issues:

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).

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).

• 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=7023735

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 (bnc#1151350).
• CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).
• CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).
• CVE-2019-14835: 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 have used this flaw to increase their privileges on the host (bnc#1150112).
• CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).
• CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).
• CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).
• CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).
• CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).
• CVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free. (bnc#1149626).
• CVE-2019-15921: There was a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c (bnc#1149602).
• CVE-2018-21008: A use-after-free could have been caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).
• CVE-2019-15919: SMB2_write in fs/cifs/smb2pdu.c had a use-after-free (bnc#1149552).
• CVE-2019-15917: There was a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c…

The following security issues were fixed:

• CVE-2019-14896: A heap-based buffer overflow vulnerability was found in the Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP (bsc#1157157).
• CVE-2019-14897: A stack-based buffer overflow was found in the Marvell WiFi chip driver. An attacker was able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA (bsc#1157155).
• CVE-2019-10220: The CIFS implementation was vulnerable to a relative paths injection in directory entry lists (bsc#1144903).
• CVE-2019-17133: Fixed a Buffer Overflow in cfg80211_mgd_wext_giwessid() in net/wireless/wext-sme.c, because the function did not reject a long SSID IE (bsc#1153158).
• CVE-2019-14835: A buffer overflow flaw was fixed in the 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 (bsc#1150112).
• xen/pv: Fixed a boot up hang where domain_crash_sync was called from entry.S (bsc#1153811).
