Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
requirements.
Security Fix(es) :
* A race condition was found in the Linux kernel, present since
v3.14-rc1 through v4.12. The race happens between threads of
inotify_handle_event() and vfs_rename() while running the rename
operation against the same file. As a result of the race the next slab
data or the slab's free list pointer can be corrupted with
attacker-controlled data, which may lead to the privilege escalation.
(CVE-2017-7533, Important)
* It was found that the NFSv4 server in the Linux kernel did not
properly validate layout type when processing NFSv4 pNFS LAYOUTGET and
GETDEVICEINFO operands. A remote attacker could use this flaw to
soft-lockup the system and thus cause denial of service.
