Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： scsi: mpt3sas：在 _base_assign_reply_queues() 中避免对 cpumask_of_node() 进行越界调用 可能返回 （即 -1），这种情况出现在缺乏 PCI 设备 NUMA 拓扑信息的系统上，例如不支持设备与 NUMA 节点亲和性暴露的单插槽主板。若将 -1 直接传入 ，会导致访问 ，从而引发 UBSAN（未定义行为 sanitizers）捕获的数组越界读错误： 当无可用的 NUMA 节点时，应回退使用 ，而不是假设 始终返回有效的

Vulnerability Title
scsi: mpt3sas: Avoid out-of-bounds cpumask_of_node() call in _base_assign_reply_queues()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Avoid out-of-bounds cpumask_of_node() call in _base_assign_reply_queues()
dev_to_node() can return NUMA_NO_NODE (-1) on systems without NUMA
topology information for the PCI device, such as single-socket boards
that don't expose device-to-node affinity. Passing -1 directly into
cpumask_of_node() indexes node_to_cpumask_map[-1], an out-of-bounds
array read caught by UBSAN:
UBSAN: array-index-out-of-bounds in arch/x86/include/asm/topology.h:72:28
index -1 is out of range for type 'cpumask *[1024]'
Fall back to cpu_online_mask when no NUMA node is available, rather than
assuming dev_to_node() always returns a valid node index.
