Vulnerability from cvelistv5
Published

Modified

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Cancel reg_work before freeing device on remove c4iw_uld_state_change() queues reg_work to register the RDMA device. c4iw_remove() can free ctx->dev while this work is pending or running, leaving c4iw_register_device() accessing the freed device. Cancel reg_work before removing the device. The registration work can tear down ctx->dev when registration fails, so do not unregister or deallocate it again in that case. This issue was found by an in-house static analysis tool.

such UAFs score AC:L.\\nPR:L - Per CNA driver-removal UAF precedent, an unprivileged local user on Chelsio iWARP/HPC hosts can spray the freed c4iw_dev/ib_device while privileged or automated teardown proceeds; init-namespace root is not required for the UAF itself.\\nUI:N - No victim action such as mounting a filesystem or opening a file is required; the attacker queues reg_work and coordinates driver removal themselves, or piggybacks on routine PCI/module teardown.\\nS:U - The use-after-free corrupts the host kernel c4iw_dev/ib_device heap object within the same security authority; it is not a VM escape, IOMMU/DMA isolation bypass, or sandbox breakout.\\nC:H - After c4iw_dealloc()/ib_dealloc_device(), c4iw_register_device() still reads ctx-\u003edev (node_guid, ports, ibdev ops) from the freed ib_device; this kernel heap UAF enables arbitrary disclosure via slab reuse.\\nI:H - The dangling worker writes ibdev fields, may call ib_register_device() on freed memory, and can double-free via c4iw_dealloc(); heap spraying the ib_device ops table yields write and control-flow hijack primitives.\\nA:H - Use-after-free of c4iw_dev from workqueue context during remove causes a kernel oops or panic even when not fully exploited, so availability impact is High.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"e6e79e7be87c5ea92728060a3d7fb56890a91e45\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"672ee1981db10569ec96030bddb322f18382ec04\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"4681e731db07769846901cfabdd3e53f765eb9d3\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"3265d558dfafab8f12f5fba06ebbf15cae9f3225\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"fe9c591026c576d8b1f72aab5e4cd67350530763\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"85f438382a865a4dc4c50e6b884310bb2b60fc4d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"320e5258a53af0abc5abd9eb01519a48bab2dee8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1c8f1da5d851b92aeb81dbbb9ebd516f6e2588f5\", \"lessThan\": \"a7100601aa1a39f799a566acce10db20eaf4b7f2\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/infiniband/hw/cxgb4/device.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.15\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.15\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.270\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.221\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.188\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.157\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.109\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.50\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2.4\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.2.*\"}, {\"status\": \"unaffected\", \"version\": \"7.3\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/infiniband/hw/cxgb4/device.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/e6e79e7be87c5ea92728060a3d7fb56890a91e45\"}, {\"url\": \"https://git.kernel.org/stable/c/672ee1981db10569ec96030bddb322f18382ec04\"}, {\"url\": \"https://git.kernel.org/stable/c/4681e731db07769846901cfabdd3e53f765eb9d3\"}, {\"url\": \"https://git.kernel.org/stable/c/3265d558dfafab8f12f5fba06ebbf15cae9f3225\"}, {\"url\": \"https://git.kernel.org/stable/c/fe9c591026c576d8b1f72aab5e4cd67350530763\"}, {\"url\": \"https://git.kernel.org/stable/c/85f438382a865a4dc4c50e6b884310bb2b60fc4d\"}, {\"url\": \"https://git.kernel.org/stable/c/320e5258a53af0abc5abd9eb01519a48bab2dee8\"}, {\"url\": \"https://git.kernel.org/stable/c/a7100601aa1a39f799a566acce10db20eaf4b7f2\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nRDMA/cxgb4: Cancel reg_work before freeing device on remove\\n\\nc4iw_uld_state_change() queues reg_work to register the RDMA device.\\nc4iw_remove() can free ctx-\u003edev while this work is pending or running,\\nleaving c4iw_register_device() accessing the freed device.\\n\\nCancel reg_work before removing the device.
