A remote peer supplying the VLAN frame cannot alone trigger it.\nAC:L - The attacker controls both sides of the race — two threads looping on recvmmsg(MSG_PEEK) over the same socket — and controls the packet contents and size, so the window can be retried indefinitely until won, as syzbot's reproducer demonstrates.\nPR:L - Creating the packet socket requires CAP_NET_RAW, but packet_create() checks ns_capable(net->user_ns, CAP_NET_RAW), so any unprivileged user obtains it via `unshare -Urn` and can self-supply the VLAN-tagged frame on loopback inside that namespace.\nUI:N - The attacker performs every step itself — creating the socket, injecting the VLAN frame, and issuing the concurrent MSG_PEEK receives. No victim action is involved.\nS:U - The corruption and its consequences are confined to the kernel's own memory and the attacking process's socket; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - The non-atomic save/restore lets an inflated skb->len persist on a queued (MSG_PEEK'd) skb while skb->data stays put, so skb_copy_datagram_msg() copies an attacker-growable number of bytes past skb->tail — slab tailroom and, with a size-groomed packet, skb_shared_info kernel pointers — directly into the user's buffer.\nI:L - The race durably corrupts kernel skb metadata (skb->data driven outside the head buffer, skb->len inflated without bound) under attacker influence, but the affected path only reads through those fields, yielding no arbitrary kernel write or control-flow primitive.\nA:H - The demonstrated outcome is skb_push() driving skb->data below skb->head, hitting skb_under_panic() -> BUG() — an invalid-opcode Oops that panics the box outright under panic_on_oops, common in cloud, embedded, and automotive deployments." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
