Reaching the code therefore requires local access.\nAC:L - No race, timing window, or memory-layout precondition exists; a single unprivileged stats read deterministically triggers the 128-byte overflow, and it can be repeated at will in a loop.\nPR:L - Any unprivileged local user can trigger it — `/proc/net/dev` and `/sys/class/net/*/statistics/*` require no capability, and `ETHTOOL_GSTATS` is explicitly exempt from the `CAP_NET_ADMIN` check in `__dev_ethtool()` (net/ethtool/ioctl.c:3093), so it works even from inside an unprivileged container.\nUI:N - The attacker triggers the counter dump entirely on their own by reading interface statistics; no victim action is needed.\nS:U - The overflow corrupts kernel-owned memory within the same security authority and does not violate an IOMMU translation or cross a VM/sandbox boundary.\nC:H - A 128-byte device-DMA write past the allocation corrupts adjacent kernel memory that can hold pointers, lengths, or other metadata, and such corruption is leveragable into arbitrary kernel memory disclosure.\nI:H - This is a 128-byte out-of-bounds write performed by the NIC's DMA engine, invisible to KASAN/SLUB redzoning, and an adjacent-network attacker can influence the written values through the rx_octets/rx_pause/rx_runt/rx_mac_error tally fields — a partially controlled OOB write primitive.\nA:H - Repeated DMA writes into memory the kernel may have allocated for other purposes corrupt live kernel state, leading to oops or panic, and the attacker can trigger the write continuously." } ] } ], "affected": [ {
