Title
IB/qib: Protect from buffer overflow in struct qib_user_sdma_pkt fields
Summary
In the Linux kernel, the following vulnerability has been resolved: IB/qib: Protect from buffer overflow in struct qib_user_sdma_pkt fields Overflowing either addrlimit or bytes_togo can allow userspace to trigger a buffer overflow of kernel memory. Check for overflows in all the places doing math on user controlled buffers.

it is not triggered by remote InfiniBand packet processing.\\nAC:L - The attacker fully controls iovec lengths and PBC/header fields that drive the overflowing arithmetic, so the heap overflow can be triggered reliably once the QIB device is present and SDMA is running.\\nPR:L - No capabilities are checked on the open/assign/writev path; access is only gated by /dev/ipath permissions, and this userspace SDMA interface is intended for unprivileged PSM/MPI processes on systems with the HCA.\\nUI:N - The attacker opens the device and issues crafted write/writev calls themselves; no separate victim action is required.\\nS:U - Impact is kernel memory corruption and privilege escalation on the same host authority, not a cross-boundary escape (VM/IOMMU/sandbox).\\nC:H - A controllable kernel heap buffer overflow can be leveraged for arbitrary kernel memory disclosure.\\nI:H - Kernel heap overflow of qib_user_sdma_pkt addr[]/adjacent memory enables arbitrary write and control-flow hijacking for full integrity compromise.\\nA:H - The same heap corruption can cause kernel oops/panic or hang, fully impacting availability.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"bda41654b6e0c125a624ca35d6d20beb8015b5d0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"3f57c3f67fd93b4da86aeffea1ca32c484d054ad\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"60833707b968d5ae02a75edb7886dcd4a957cf0d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"73d2892148aa4397a885b4f4afcfc5b27a325c42\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"0f8cdfff06829a0b0348b6debc29ff6a61967724\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"c3e17e58f571f34c51aeb17274ed02c2ed5cf780\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"0d4395477741608d123dad51def9fe50b7ebe952\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f931551bafe1f10ded7f5282e2aa162c267a2e5d\", \"lessThan\": \"d39bf40e55e666b5905fdbd46a0dced030ce87be\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/infiniband/hw/qib/qib_user_sdma.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2.6.35\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"2.6.35\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.4.292\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.4.*\"}, {\"status\": \"unaffected\", \"version\": \"4.9.290\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.9.*\"}, {\"status\": \"unaffected\", \"version\": \"4.14.255\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.14.*\"}, {\"status\": \"unaffected\", \"version\": \"4.19.216\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.157\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.77\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.14.16\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.14.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/infiniband/hw/qib/qib_user_sdma.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/bda41654b6e0c125a624ca35d6d20beb8015b5d0\"}, {\"url\": \"https://git.kernel.org/stable/c/3f57c3f67fd93b4da86aeffea1ca32c484d054ad\"}, {\"url\": \"https://git.kernel.org/stable/c/60833707b968d5ae02a75edb7886dcd4a957cf0d\"}, {\"url\": \"https://git.kernel.org/stable/c/73d2892148aa4397a885b4f4afcfc5b27a325c42\"}, {\"url\": \"https://git.kernel.org/stable/c/0f8cdfff06829a0b0348b6debc29ff6a61967724\"}, {\"url\": \"https://git.kernel.org/stable/c/c3e17e58f571f34c51aeb17274ed02c2ed5cf780\"}, {\"url\": \"https://git.kernel.org/stable/c/0d4395477741608d123dad51def9fe50b7ebe952\"}, {\"url\": \"https://git.kernel.org/stable/c/d39bf40e55e666b5905fdbd46a0dced030ce87be\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nIB/qib: Protect from buffer overflow in struct qib_user_sdma_pkt fields\\n\\nOverflowing either addrlimit or bytes_togo can allow userspace to trigger\\na buffer overflow of kernel memory.
