  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: mpt3sas: Avoid out-of-bounds cpumask_of_node() call in _base_assign_reply_queues()\n\ndev_to_node() can return NUMA_NO_NODE (-1) on systems without NUMA\ntopology information for the PCI device, such as single-socket boards\nthat don't expose device-to-node affinity. Passing -1 directly into\ncpumask_of_node() indexes node_to_cpumask_map[-1], an out-of-bounds\narray read caught by UBSAN:\n\n  UBSAN: array-index-out-of-bounds in arch/x86/include/asm/topology.h:72:28\n  index -1 is out of range for type 'cpumask *[1024]'\n\nFall back to cpu_online_mask when no NUMA node is available, rather than\nassuming dev_to_node() always returns a valid node index.",
