This update for the Linux Kernel 4.4.114-92_64 fixes several issues.
The following security issues were fixed :
CVE-2017-13166: Prevent elevation of privilege vulnerability in the v4l2 video driver (bsc#1085447).
CVE-2018-1068: A flaw in the implementation of 32-bit syscall interface for bridging allowed a privileged user to arbitrarily write to a limited range of kernel memory (bsc#1085114).
CVE-2018-7566: Prevent buffer overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user (bsc#1083488).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
