This update for the Linux Kernel 4.12.14-195 fixes several issues.
The following security issue was fixed:
- CVE-2019-14835: A buffer overflow flaw was found in the way vhost functionality, that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration.

The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive
various security and bugfixes.
The following security bugs were fixed:
- CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP
ID values the kernel produces for connection-less protocols. When such
traffic was sent to multiple destination IP addresses, it was possible to
obtain hash collisions (of indices to the counter array) and thereby obtain
the hashing key (via enumeration). An attack could have been conducted by
hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to
attacker-controlled IP addresses. [bn
