    Summary: Updated kernel packages fix security vulnerabilities

    Details: This kernel update is based on the upstream 4.14.25 and updates the KPTI mitigation for Meltdown (CVE-2017-5754) on 32bit x86. It also adds ome optimizations and improvements to mitigate some of the slowdons caused by the Meltdown (CVE-2017-5754) and Spectre, variant 2 (CVE-2017-5715). Other security fixes in this update: The netfilter subsystem in the Linux kernel through 4.15.7 mishandles the case of a rule blob that contains a jump but lacks a user-defined chain, which allows local users to cause a denial of service (NULL pointer dereference) by leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in net/ipv6/netfilter/ip6_tables.c (CVE-2018-1065). Other changes in this update: WireGuard has been updated to 0.0.20180304. A fix in the scsi subsystem that prevents the kernel to hang or oops, triggered at least when trying to mount some raid6 setups (mga#22704). input/goodix: add support for GDIX1002 (mga#22703) For other upstream fixes in this update, read the referenced changelogs.
