"baseScore": 7.1, "baseSeverity": "HIGH"}, "scenarios": [{"lang": "en", "value": "AV:L - The bug is triggered by transmitting on virtual CAN interfaces (vcan/vxcan) via AF_CAN or packet sockets, which requires local system access rather than remote network or adjacent CAN-bus reachability.\nAC:L - An attacker who can send on a vcan/vxcan interface reliably hits the bad `priv->ctrlmode` read on every TX; no race or uncontrolled external condition is required.\nPR:L - An unprivileged user can create vcan in a user namespace (CAP_NET_ADMIN via userns) or send on an existing vcan with AF_CAN, which needs no elevated capability beyond a basic local account.\nUI:N - Exploitation requires only attacker-controlled socket sends on the virtual CAN device; no victim action is needed.\nS:U - Impact remains within the local kernel/host authority; this is not a VM escape, IOMMU bypass, or other cross-boundary breakout.\nC:H - The defect is a CWE-125 out-of-bounds/wrong-object read of kernel memory via a miscast `can_priv`; per kernel OOB-read guidance this is scored High when severity is uncertain.\nI:N - The bad access is read-only and only influences whether an skb is dropped; it provides no write primitive or control-flow hijack.\nA:H - When the misread bits look like CAN_CTRLMODE_LISTENONLY, TX frames on vcan/vxcan are dropped, enabling a complete DoS of that interface\u2019s transmit path."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git",
