Summary

In the Linux kernel, the following vulnerability has been resolved: aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts This patch is against CVE-2023-6270. The description of cve is: A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution. In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial code is finished. But the net_device ifp will still be used in later tx()->dev_queue_xmit() in kthread. Which means that the dev_put(ifp) should NOT be called in the success path of skb initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into use-after-free because the net_device is freed. This patch removed the dev_put(ifp) in the success path in aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

The description of cve is:\n\n  A flaw was found in the ATA over Ethernet (AoE) driver in the Linux\n  kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on\n  `struct net_device`, and a use-after-free can be triggered by racing\n  between the free on the struct and the access through the `skbtxq`\n  global queue. This could lead to a denial of service condition or\n  potential code execution.\n\nIn aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial\ncode is finished. But the net_device ifp will still be used in\nlater tx()-\u003edev_queue_xmit() in kthread. Which means that the\ndev_put(ifp) should NOT be called in the success path of skb\ninitial code in aoecmd_cfg_pkts(). Otherwise tx() may run into\nuse-after-free because the net_device is freed.\n\nThis patch removed the dev_put(ifp) in the success path in\naoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx()."

The description of cve is:\n\n  A flaw was found in the ATA over Ethernet (AoE) driver in the Linux\n  kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on\n  `struct net_device`, and a use-after-free can be triggered by racing\n  between the free on the struct and the access through the `skbtxq`\n  global queue. This could lead to a denial of service condition or\n  potential code execution.\n\nIn aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial\ncode is finished. But the net_device ifp will still be used in\nlater tx()-\u003edev_queue_xmit() in kthread. Which means that the\ndev_put(ifp) should NOT be called in the success path of skb\ninitial code in aoecmd_cfg_pkts(). Otherwise tx() may run into\nuse-after-free because the net_device is freed.\n\nThis patch removed the dev_put(ifp) in the success path in\naoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx()."

              "value": "AV:L - `aoecmd_cfg_pkts()` is reachable only from `aoecmd_cfg()`, whose callers are the module\u0027s 60-second `discover_timer` (drivers/block/aoe/aoemain.c:21), writes to the local char devices `/dev/etherd/discover` and `/dev/etherd/revalidate` (drivers/block/aoe/aoechr.c:74,114), and `aoeblk_release()` on last close of an AoE block device; no inbound AoE frame path (`aoenet_rcv` \u2192 `aoecmd_cfg_rsp`) reaches it, so local access is required.\nAC:L - The attacker controls both sides of the race: the queueing side can be driven at will (each `write()` to `/dev/etherd/discover` enumerates every `init_net` netdev and pushes an skb holding an unreferenced `skb-\u003edev` onto the global `skbtxq`, and the kernel timer does it unprompted every 60s), while the window between the erroneous `dev_put(ifp)` and the deferred `dev_queue_xmit(skb)` in the `aoe_tx` kthread is widened arbitrarily by flooding `skbtxq` and loading the CPU; init_net netdev teardown is either directly inducible (e.g. `PPPIOCNEWUNIT`/close on `/dev/ppp`, which carries no capability check) or occurs routinely from container veth churn, VPN teardown and NIC hotplug, so the attack is repeatable until it succeeds.\nPR:L - No capability check exists anywhere on the path \u2014 `aoechr_open()` only validates the minor number, and access is gated purely by file permissions on `/dev/etherd/*`, which distro aoetools udev rules grant to the unprivileged `disk` group; an ordinary local user with that access (or with any AoE block device fd, via the `aoeblk_release()` path) can drive discovery, and the periodic timer keeps the vulnerable code executing even with zero attacker action.\nUI:N - The discovery packets are generated by the attacker\u0027s own writes or by the driver\u0027s automatic one-minute timer, and the freed `net_device` is dereferenced in the `aoe_tx` kthread; no action by any other user is required.\nS:U - The freed `struct net_device` and the code that dereferences it both live in the kernel\u0027s own security authority; this is in-kernel memory corruption, not a VM, IOMMU or sandbox boundary crossing.\nC:H - This is a use-after-free on a `struct net_device` whose contents the attacker can reclaim via heap spraying; `tx()` reads `ifp-\u003ename` into a `pr_warn()` (leaking freed heap contents to dmesg) and `dev_queue_xmit()` walks `dev-\u003eflags`, `dev-\u003e_tx`, `dev-\u003enum_tx_queues` and `dev-\u003enetdev_ops` from the freed object, yielding attacker-steered out-of-bounds reads of kernel memory.\nI:H - `__dev_queue_xmit()` on the freed device loads and calls function pointers (`netdev_ops-\u003endo_select_queue`, `ndo_start_xmit`, `q-\u003eenqueue`) and indexes the `dev-\u003e_tx` queue array from reclaimed, attacker-controlled memory, giving a control-flow hijack and out-of-bounds write primitive, not merely a stale read.\nA:H - Even unexploited, transmitting on a freed `net_device` reliably produces a kernel oops or panic in the `aoe_tx` kthread, and the attacker can repeat the trigger indefinitely."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
