More information can be found on https://www.suse.com/support/kb/doc/?id=7023735\n\n- CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port\n  failed to add a port, which may have caused denial of service (bsc#1152685).\n\n- CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with\n  Transactional Memory support could be used to facilitate sidechannel\n  information leaks out of microarchitectural buffers, similar to the\n  previously described 'Microarchitectural Data Sampling' attack.\n\n  The Linux kernel was supplemented with the option to disable TSX operation\n  altogether (requiring CPU Microcode updates on older systems) and better\n  flushing of microarchitectural buffers (VERW).\n\n  The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251\n\n- CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the\n  alloc_workqueue return value, leading to a NULL pointer dereference.\n  (bsc#1150457).\n\n- CVE-2019-10220: Added sanity checks on the pathnames passed to the user\n  space.
