has been resolved:\n\nBluetooth: qca: fix info leak when fetching fw build id\n\nAdd the missing sanity checks and move the 255-byte build-id buffer off\nthe stack to avoid leaking stack data through debugfs in case the\nbuild-info reply is malformed." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H", "baseScore": 8.1, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:A - The malformed build-info reply is supplied by the Bluetooth controller across the HCI/UART transport, so the attacker position is a rogue or over-the-air-compromised QCA BT SoC in Bluetooth radio range of the phone/embedded device — an adjacent-network attack surface, consistent with prior kernel-CNA scoring of HCI-transport-sourced data (CVE-2024-36968).\nAC:L - The controller deterministically chooses the event length and the length byte (e.g. a 3-byte reply with data[0]=254 for the slab overread, or data[0]=255 for the uninitialized-stack leak); there is no race, timing window, or memory-layout luck, and the path re-runs on every bring-up and subsystem restart.\nPR:N - qca_read_fw_build_info() runs unconditionally from hdev->setup during HCI device initialisation at boot/rfkill-unblock/SSR with no authentication and no host account required, and the resulting leak lands in a 0444-mode debugfs node rather than behind any credential check.\nUI:N - Bluetooth setup is performed automatically by the kernel when the HCI device is brought up; no victim action such as pairing, mounting, or opening a file is involved.\nS:U - Both the out-of-bounds reads and the disclosed data stay within the kernel's own memory and security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - This is an out-of-bounds read of up to ~254 bytes of adjacent slab memory past the skb buffer plus an unbounded kernel-stack overread (vsnprintf \"%s\" over a never-initialised 255-byte stack buffer), repeatable on every controller reset and exfiltrated through debugfs — far beyond a small bounded read, and sufficient to recover kernel pointers and defeat KASLR.\nI:N - The defect is purely a read overrun; the leaked bytes are written into a correctly sized kvasprintf allocation, so no kernel data outside the driver's own fw_info string is modified.\nA:H - The unbounded string walk off the end of the 255-byte stack buffer can run into the VMAP_STACK guard page, and the slab overread can hit a KFENCE-guarded page, producing an oops during Bluetooth initialisation — a panic on the panic_on_oops/panic_on_warn configurations common in Android, automotive, and embedded deployments." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected",
