  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched/membarrier: reduce the ability to hammer on sys_membarrier\n\nOn some systems, sys_membarrier can be very expensive, causing overall\nslowdowns for everything.  So put a lock on the path in order to\nserialize the accesses to prevent the ability for this to be called at\ntoo high of a frequency and saturate the machine.",
