CAP_NET_ADMIN, which an unprivileged user obtains in a user namespace via `unshare -Urn`, and the required multiqueue device can be created there with `ip link add numtxqueues N type veth`.\nUI:N - The attacker performs the configuration and packet transmission entirely on their own; no victim action is required.\nS:U - The out-of-bounds access and its consequences remain within the kernel's security scope with no crossing of a VM/IOMMU boundary.\nC:H - The attacker-controlled index produces an out-of-bounds read of `q->qdiscs[]` and out-of-range queue selection, a memory-disclosure primitive over kernel memory that can be leveraged to leak data.\nI:H - The OOB-read pointer is dereferenced and indirect-called (`child->ops->peek`), giving a control-flow hijack primitive from
