Title
IB/IPoIB: Fix legacy IPoIB due to wrong number of queues
Summary
In the Linux kernel, the following vulnerability has been resolved: IB/IPoIB: Fix legacy IPoIB due to wrong number of queues The cited commit creates child PKEY interfaces over netlink will multiple tx and rx queues, but some devices doesn't support more than 1 tx and 1 rx queues. This causes to a crash when traffic is sent over the PKEY interface due to the parent having a single queue but the child having multiple queues. This patch fixes the number of queues to 1 for legacy IPoIB at the earliest possible point in time.

it is not triggered by remote InfiniBand/IP packet parsing.\\nAC:L - On legacy IPoIB, netlink children are deterministically given multiple TX queues while sharing one unlocked tx_ring; an attacker who sends from multiple threads controls both sides of the resulting concurrent-xmit race, so no attacker-uncontrollable condition is required.\\nPR:L - Child creation needs only CAP_NET_ADMIN in the netns user_ns (netlink_net_capable), which is available via user namespaces/containers with a delegated IPoIB parent; once such a child exists from normal PKEY setup, an unprivileged local sendto triggers the corruption.\\nUI:N - The attacker creates the PKEY child and/or sends the traffic themselves; no separate victim mount, open, or other interaction is required.\\nS:U - Impact is a host-kernel oops/memory corruption within the same kernel security authority, with no VM escape, IOMMU bypass, or other cross-boundary effect.\\nC:H - Multiple netdev TX queues concurrently enter legacy ipoib_send on one shared tx_ring/tx_head, causing skb UAF/double-free and slab freelist corruption (as in the kmem_cache_alloc oops), which yields a high-impact read primitive.\\nI:H - The same concurrent multi-queue use of the single tx_ring is memory corruption/UAF that can be turned into heap control and arbitrary write or control-flow hijack, not a pure crash-only fault.\\nA:H - The reported path is a kernel NULL-pointer oops/panic when traffic is sent over the misconfigured PKEY interface, which is High availability impact.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"d4bf3fcccd188db9f3310d93472041cdefba97bf\", \"lessThan\": \"4a779187db39b2f32d048a752573e56e4e77807f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"d21714134505bc23daa0455b295f3b63730b3b42\", \"lessThan\": \"b1afb666c32931667c15ad1b58e7203f0119dcaf\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ca48174a7643a7e6dd31c4338c5cde49552e138e\", \"lessThan\": \"1b4ef90cbcfa603b3bb536fbd6f261197012b6f6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ee0e9b2c4b9c35837553124b4912230a7e7c7212\", \"lessThan\": \"7197460dcd43ff0e4a502ba855dd82d37c2848cc\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"dbc94a0fb81771a38733c0e8f2ea8c4fa6934dc1\", \"lessThan\": \"e632291a2dbce45a24cddeb5fe28fe71d724ba43\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"2aecfec735f16f99c059db956edfd95a32458d22\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8fa3ee8ef185eb3e8be44f282721b05a03e6f888\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bc2f5760b47cba4a76be9371806f8f10fccf71a9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bab775fa9c4f4b4da30c9cc99be4bec19fb01659\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4.9.337\", \"lessThan\": \"4.10\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"4.14.303\", \"lessThan\": \"4.15\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"4.19.270\", \"lessThan\": \"4.20\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"6.0.16\", \"lessThan\": \"6.1\", \"versionType\": \"semver\"}], \"programFiles\": [\"drivers/infiniband/ulp/ipoib/ipoib_main.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.4.229\", \"lessThan\": \"5.4.232\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"5.10.163\", \"lessThan\": \"5.10.168\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"5.15.86\", \"lessThan\": \"5.15.94\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"6.1.2\", \"lessThan\": \"6.1.12\", \"versionType\": \"semver\"}], \"programFiles\": [\"drivers/infiniband/ulp/ipoib/ipoib_main.c\"], \"defaultStatus\": \"unaffected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/4a779187db39b2f32d048a752573e56e4e77807f\"}, {\"url\": \"https://git.kernel.org/stable/c/b1afb666c32931667c15ad1b58e7203f0119dcaf\"}, {\"url\": \"https://git.kernel.org/stable/c/1b4ef90cbcfa603b3bb536fbd6f261197012b6f6\"}, {\"url\": \"https://git.kernel.org/stable/c/7197460dcd43ff0e4a502ba855dd82d37c2848cc\"}, {\"url\": \"https://git.kernel.org/stable/c/e632291a2dbce45a24cddeb5fe28fe71d724ba43\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nIB/IPoIB: Fix legacy IPoIB due to wrong number of queues\\n\\nThe cited commit creates child PKEY interfaces over netlink will\\nmultiple tx and rx queues, but some devices doesn\u0027t support more than 1\\ntx and 1 rx queues.
