"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfuse: publish io-uring queues with release semantics\n\nfuse_uring_create_queue() initializes a fuse_ring_queue and then\npublishes the pointer into ring->queues[qid] with WRITE_ONCE() under the\nfch->lock. There are several readers that may concurrently be fetching\nthat pointer locklessly and then deferencing it.\n\nWRITE_ONCE() doesn't ensure ordering of the queue's field\ninitialization before the ring->queues[qid] pointer assignment. The\nqueue must be published with smp_store_release() so the field\ninitialization is guaranteed to happen before.\n\nReaders in paths where the read may happen concurrently with the store\nneed to use READ_ONCE() because any race involving a plain access is\nundefined."
