Red Hat Enterprise Linux 6 and CentOS 6 Receive Important Kernel Security Update

Marked by the Red Hat Product Security team as having a security impact of “Important,” the new Linux kernel security update is here to patch a memory corruption (CVE-2018-9568) that occurred due to incorrect socket cloning and a NULL pointer dereference (CVE-2019-11810) discovered in drivers/scsi/megaraid/megaraid_sas_base.c, which could lead to a denial of service. Also fixed in this update are two bugs affecting the performance of the Linux kernel on Red Hat Enterprise Linux 6 and CentOS Linux 6 systems, namely a fragmented packets timing out issue and the backport TCP follow-up for small buffers. These two bugs can be corrected if you install the new kernel versions for your operating system.
