Remote RoCE traffic can influence counter values but cannot itself invoke the vulnerable statistics refresh.\nAC:L - No race or condition outside the attacker's control is required; on an affected pre-P5/P7 adapter, an attacker can repeatedly and reliably request statistics. The required driver and supported hardware define the affected component rather than adding attack complexity.\nPR:L - The sysfs counter files are world-readable with mode 0444, and RDMA_NLDEV_CMD_STAT_GET has no RDMA_NL_ADMIN_PERM check. An ordinary unprivileged local user can therefore trigger the overwrite without capabilities or user namespaces.\nUI:N - The attacker directly triggers the vulnerable counter refresh, requiring no action by another user.\nS:U - The corruption occurs within the host kernel reached by the local attacker and does not inherently cross a VM, IOMMU, or other security-authority boundary.\nC:H - The three 64-bit stores cross into an adjacent heap object, enabling corruption of kernel objects that can plausibly be developed into control-flow and arbitrary-memory-access primitives, including disclosure of sensitive kernel memory.\nI:H - The function performs three out-of-bounds 64-bit writes 160, 168, and 176 bytes beyond the allocated counter array. Corruption of an adjacent heap object can support arbitrary kernel modification or code execution.\nA:H - The heap overwrite can corrupt pointers or other critical kernel state, causing an oops, panic, or complete system failure, and the unprivileged attacker can trigger it repeatedly."
