Severity ?
8.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: s390/vfio_ccw: Selectively expand io_mutex The io_mutex was defined to serialize the io_regions, but then has also sort of been associated with the I/O themselves because of the close relationship they share. With the handful of races that are possible, the choices are either to: A) expand the scope of io_mutex to close these remaining windows, or B) reduce the scope of io_mutex to just io_region, and introduce a new lock mechanism for the remaining I/O resources This patch implements A, since B brings with it a lot more interactions that would need to be tracked and kept in a correct hierarchy. It also takes advantage of the workqueue element for cp_free() that now gets called out of fsm_notoper(), which could be invoked out of an interrupt context and thus cannot acquire a mutex itself.

The bug is reached only through local VFIO mediated-device syscalls (read/write/ioctl on vfio-ccw device fds) and deferred work from hardware I/O interrupts and channel-path events; vfio-ccw has no network, Bluetooth, or physical-bus entry point.\\nAC:L - The VFIO client controls both sides of each race window: it can submit channel I/O, close or reset the device, and trigger DMA unmap while io_work, notoper_work, or fsm_close concurrently run cp_free, cp_update_scsw, or cp_iova_pinned without full io_mutex protection, and retry to win reliably.\\nPR:L - Exploitation requires an opened vfio-ccw mdev device fd (typical QEMU/libvirt VM operator or delegated /dev/vfio holder on IBM Z passthrough hosts), not init-namespace root; mdev creation is admin setup, but triggering the races needs only that delegated VFIO client access.\\nUI:N - No separate victim action is required; once vfio-ccw passthrough is configured, the attacker issues concurrent channel I/O, region access, device close/reset, or DMA unmap without needing another user to mount media or interact.\\nS:C - On IBM Z/LinuxONE, vfio-ccw passes DASD/CCW subchannels into KVM guests; guest-driven channel I/O and path events trigger host interrupt/workqueue activity concurrent with VFIO client teardown, corrupting hypervisor kernel memory outside the VM security boundary.\\nC:H - cp_free racing with cp_update_scsw, cp_iova_pinned, and io_region access without io_mutex causes use-after-free on ccwchain_list and page_array structures; per kernel UAF guidance this enables attacker-influenced heap reuse and arbitrary kernel read primitives.\\nI:H - Concurrent cp_free during cp_init, page_array_unpin_free, memcpy into io_region, and mutex operations on freed channel_program memory provides heap-sprayable arbitrary write and control-flow hijack potential beyond a simple crash.\\nA:H - Use-after-free and double-free of channel program structures during concurrent I/O completion, not-operational cleanup, or device close can immediately oops or panic the host kernel from invalid list/mutex access, and successful exploitation can crash or hang the system.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"dab6a6627b0b0cce23653e99c7b0bf8c6cfd82e0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"56d7488533ceac4e986e96e15c9e487a2245bc01\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"f72a51810d49411bd8cad0c2df8592320a2fe5cc\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"2ba9efdf9ebedc4e54df4b56aa3b43a65f7967cd\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"b6aecea4b2b246f9fbd98a5712daa1193a60818e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"2a5ac0c0f1f7da33929211a2e41911bf72ee35d8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"4f76617378ee97c557b526cb58d3c61eb0a9c963\", \"lessThan\": \"34f4feff3e90bd09308fad0974e97113b23b812a\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/s390/cio/vfio_ccw_chp.c\", \"drivers/s390/cio/vfio_ccw_cp.c\", \"drivers/s390/cio/vfio_ccw_drv.c\", \"drivers/s390/cio/vfio_ccw_fsm.c\", \"drivers/s390/cio/vfio_ccw_private.h\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.2\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.2\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.15.218\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.185\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.153\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.105\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.46\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.10\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/s390/cio/vfio_ccw_chp.c\", \"drivers/s390/cio/vfio_ccw_cp.c\", \"drivers/s390/cio/vfio_ccw_drv.c\", \"drivers/s390/cio/vfio_ccw_fsm.c\", \"drivers/s390/cio/vfio_ccw_private.h\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/dab6a6627b0b0cce23653e99c7b0bf8c6cfd82e0\"}, {\"url\": \"https://git.kernel.org/stable/c/56d7488533ceac4e986e96e15c9e487a2245bc01\"}, {\"url\": \"https://git.kernel.org/stable/c/f72a51810d49411bd8cad0c2df8592320a2fe5cc\"}, {\"url\": \"https://git.kernel.org/stable/c/2ba9efdf9ebedc4e54df4b56aa3b43a65f7967cd\"}, {\"url\": \"https://git.kernel.org/stable/c/b6aecea4b2b246f9fbd98a5712daa1193a60818e\"}, {\"url\": \"https://git.kernel.org/stable/c/2a5ac0c0f1f7da33929211a2e41911bf72ee35d8\"}, {\"url\": \"https://git.kernel.org/stable/c/34f4feff3e90bd09308fad0974e97113b23b812a\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ns390/vfio_ccw: Selectively expand io_mutex\\n\\nThe io_mutex was defined to serialize the io_regions, but then has\\nalso sort of been associated with the I/O themselves because of\\nthe close relationship they share.\\n\\nWith the handful of races that are possible, the choices are either to:\\n A) expand the scope of io_mutex to close these remaining windows, or\\n B) reduce the scope of io_mutex to just io_region, and introduce a new\\n    lock mechanism for the remaining I/O resources\\n\\nThis patch implements A, since B brings with it a lot more interactions\\nthat would need to be tracked and kept in a correct hierarchy.
