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).

• 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.

• CVE-2019-14901: A heap overflow flaw was found in the Linux kernel in Marvell WiFi chip driver. The vulnerability allowed a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system (bnc#1157042).
• CVE-2019-14895: A heap-based buffer overflow was discovered in the Linux kernel in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could have allowed the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).
• CVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).

There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).
