"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsysctl: Fix data races in proc_douintvec_minmax().\n\nA sysctl variable is accessed concurrently, and there is always a chance\nof data-race. So, all readers and writers need some basic protection to\navoid load/store-tearing.\n\nThis patch changes proc_douintvec_minmax() to use READ_ONCE() and\nWRITE_ONCE() internally to fix data-races on the sysctl side. For now,\nproc_douintvec_minmax() itself is tolerant to a data-race, but we still\nneed to add annotations on the other subsystem's side."
