Description

In the Linux kernel, the following vulnerability has been resolved:

sched/membarrier: reduce the ability to hammer on sys_membarrier

On some systems, sys_membarrier can be very expensive, causing overall

slowdowns for everything. So put a lock on the path in order to

serialize the accesses to prevent the ability for this to be called at

too high of a frequency and saturate the machine.

Solution(s)

  • oracle-linux-upgrade-kernel

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
