No race or condition outside the attacker's practical influence is required.\nPR:N - LIO supports AuthMethod=None and dynamic initiator ACLs, allowing a remote attacker to establish a normal iSCSI session without credentials in a reasonable permissive deployment.\nUI:N - Exploitation requires only attacker-generated sessions and SCSI commands, without any victim action.\nS:U - Through the network iSCSI path, the vulnerable target-core code and the affected kernel availability remain within the same host security authority.\nC:N - The failed allocation produces a fixed NULL destination rather than an attacker-controlled read primitive, and no kernel data is disclosed.\nI:N - The attempted copy targets unmapped address zero and faults instead of modifying a live kernel object; it does not provide an arbitrary or useful write primitive.\nA:H - The NULL-destination memcpy can cause a kernel oops or panic, and a remote initiator can repeat the trigger to disrupt the target or
