network protocols.\nAC:L - Attacker fully controls fsp->location and can reliably trigger the OOB read with a single crafted ethtool ioctl; no race or attacker-uncontrollable condition is required.\nPR:L - ETHTOOL_GRXCLSRULE is explicitly exempt from CAP_NET_ADMIN in __dev_ethtool, so any unprivileged local user who can open a socket and see the interface can invoke the path.\nUI:N - No victim interaction is required; the attacker issues the ioctl directly.\nS:U - Impact is confined to the local kernel (info leak and/or oops); it does not cross VM, IOMMU, or other security-authority boundaries.\nC:H - Attacker-controlled u32 index yields an unbounded out-of-bounds read of kernel memory that is copied back to userspace as ip4dst, enabling arbitrary relative kernel memory disclosure (not a few fixed bytes).\nI:N - The defect is a pure out-of-bounds read with no write primitive or memory corruption that could modify kernel state or hijack control flow.\nA:H - A sufficiently large location reads unmapped memory and can cause a kernel oops/panic, fully disrupting availability on the device." } ] } ], "affected": [ { "product": "Linux", "vendor":
