The attacker can generate repeated RSCNs rather than depending on an uncontrollable condition.\nPR:N - The interrupt and RSCN-processing path contains no Linux privilege or user-authentication check. A fabric peer needs no privileges on the victim host.\nUI:N - Processing occurs automatically in the HBA interrupt, delayed-work, and DPC paths without victim action.\nS:U - The fault affects the kernel and storage resources governed by the same host security authority and does not cross a virtualization or isolation boundary.\nC:N - The vulnerable path performs a read through NULL at offset 0xf8 and faults before freeing or modifying memory. It provides no information-disclosure primitive.\nI:N - This is a pure NULL-pointer dereference rather than a use-after-free, out-of-bounds access, or attacker-controlled write. No data modification or control-flow primitive is exposed.\nA:H - The dereference produces a kernel oops and can panic the system or terminate the qla2xxx DPC thread, disrupting all storage handled by the affected adapter.
