An update for kernel is now available for Red Hat Enterprise Linux 6.7 ExtendedUpdate Support.Red Hat Product Security has rated this update as having a security impact ofImportant.

A Common Vulnerability Scoring System (CVSS) base score, which givesa detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
The kernel packages contain the Linux kernel, the core of any Linux operatingsystem.Security Fix(es):* It was found that the RFC 5961 challenge ACK rate limiting as implemented inthe Linux kernel’s networking subsystem allowed an off-path attacker to leakcertain information about a given connection by creating congestion on theglobal challenge ACK rate limit counter and then measuring the changes byprobing packets.

An off-path attacker could use this flaw to either terminateTCP connection and/or inject payload into non-secured TCP connection between twoendpoints on the network. (CVE-2016-5696, Important)Red Hat would like to thank Yue Cao (Cyber Security Group of the CS departmentof University of California in Riverside) for reporting this issue.Bug Fix(es):* When an interrupt request occurred and the new API was scheduled on adifferent CPU, the enic driver previously generated a warning message.

Thisbehavior was caused by a race condition between the vnic_intr_unmask() functionand the enic_poll_unlock_napi() function.

This update fixes the napi_poll()function to unlock before unmasking the interrupt.

As a result, the warningmessage no longer occurs in the described situation. (BZ#1351192)
