  "description": "In the Linux kernel, the following vulnerability has been resolved:  sysctl: Fix data races in proc_douintvec_minmax().  A sysctl variable is accessed concurrently, and there is always a chance of data-race.  So, all readers and writers need some basic protection to avoid load/store-tearing.  This patch changes proc_douintvec_minmax() to use READ_ONCE() and WRITE_ONCE() internally to fix data-races on the sysctl side.  For now, proc_douintvec_minmax() itself is tolerant to a data-race, but we still need to add annotations on the other subsystem\u0027s side.",
