Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 3.12.74-60_64_96 fixes one issue.

The following security issue was fixed :

CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free) (bsc#1131390).

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.
