    PCI: plda: Fix use-after-free of event IRQs during teardown

    In the Linux kernel, the following vulnerability has been resolved: PCI: plda: Fix use-after-free of event IRQs during teardown plda_pcie_irq_domain_deinit() removes pcie->event_domain via irq_domain_remove(), but the per-event IRQs mapped from that domain are requested with devm_request_irq() in plda_init_interrupts(). The actual free_irq() for a devm-managed IRQ is deferred by devres until after the calling probe()/remove() function returns. This means irq_domain_remove() can free the domain's internal data before the deferred free_irq() for IRQs still mapped into it has run. When devres later processes that deferred cleanup, it can end

    PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()

    In the Linux kernel, the following vulnerability has been resolved: PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts() plda_init_interrupts() initializes IRQ domains and creates IRQ mapping but does not unwind them when later step fails. If platform_get_irq() or either irq_create_mapping() fails in plda_init_interrupts(), the domains are never deinitialized. If irq_create_mapping() fails, port->intx_irq stays initialized. Hence, remove the IRQ domains in the error path by calling plda_pcie_irq_domain_deinit(). Since plda_pcie_irq_domain_deinit() now disposes of the intx_irq and msi_irq mappings itself before rem

    iommu/amd: Put PCI device after handling PPR faults

    In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Put PCI device after handling PPR faults iommu_call_iopf_notifier() looks up the requester with pci_get_domain_bus_and_slot(), which returns a PCI device with its reference count incremented. Neither the successful iommu_report_device_fault() path nor the abort path drops that reference, so every handled PPR request leaks a PCI device reference. This is the same ownership rule that was fixed for the old iommu_v2 ppr_notifier() path by commit 6cf0981c2233 ("iommu/amd: Fix pci device refcount leak in ppr_notifier()"), but iommu_call_iopf_notifier() was added late

    iommu/msm: Unwind probe state on registration failure

    In the Linux kernel, the following vulnerability has been resolved: iommu/msm: Unwind probe state on registration failure msm_iommu_probe() adds its devm-managed IOMMU object to qcom_iommu_devices before adding the IOMMU sysfs device and registering it with the IOMMU core. If iommu_device_sysfs_add() fails, probe returns with the object still on qcom_iommu_devices. The driver core then releases the devm allocation, leaving a dangling list entry that later list walks may dereference. If iommu_device_register() fails, the same dangling list entry remains and the sysfs device is left registered as well. Unwind the sysfs device and global li

    iommu/sva: Set handle->dev before the SVA handle is visible

    In the Linux kernel, the following vulnerability has been resolved: iommu/sva: Set handle->dev before the SVA handle is visible iommu_attach_device_pasid() installs the new SVA attach handle in the group PASID lookup before iommu_sva_bind_device() returns. A concurrent bind can therefore find and reuse the same handle after iommu_sva_lock is dropped. handle->dev was initialized after dropping iommu_sva_lock. This leaves a window where a racing bind can return a handle whose dev pointer is still NULL. A subsequent iommu_sva_unbind_device() can then dereference it via handle->dev->iommu_group. Initialize handle->dev before releasing iommu_s

    iommu/tegra241-cmdqv: Reject a vSID wider than the SID_MATCH field

    In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Reject a vSID wider than the SID_MATCH field tegra241_vintf_init_vsid() programs the guest-provided vSID into SID_MATCH, whose VIRT_SID field spans bits [20:1] with bit 0 as the match-enable flag. The HW therefore matches only a 20-bit Stream ID. The bound check rejects only virt_sid > UINT_MAX, which admits a value far wider than the field. The write "virt_sid << 1 | 0x1" then drops every bit above 20: a virt_sid of 0x80000000 lands as SID_MATCH = 0x1, a valid match on vSID 0, so the entry aliases the wrong Stream ID. Because vdev->virt_id is guest-c

    iommu: Fix dev_iommu memory leak when device_add fails in iommu_mock_device_add

    In the Linux kernel, the following vulnerability has been resolved: iommu: Fix dev_iommu memory leak when device_add fails in iommu_mock_device_add iommu_mock_device_add() first calls iommu_fwspec_init(), which on success allocates both dev->iommu (via dev_iommu_get()) and dev->iommu->fwspec. If the subsequent device_add(dev) call fails, the error path only calls iommu_fwspec_free(dev), which frees fwspec but leaves dev->iommu still allocated. This triggers the following kmemleak report when fuzzing with Syzkaller: BUG: memory leak unreferenced object 0xffff888011e0a200 (size 192): comm "syz.1.1695", pid 24885, jiffies 4295222527 hex

    iommu/vt-d: Force requesting ACS when tboot is enabled

    In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Force requesting ACS when tboot is enabled Currently the conditions of requesting ACS in detect_intel_iommu() don't include tboot, leading to a possible misconfiguration with ACS disabled (e.g. due to user opts) while iommu is later forced on by tboot_force_iommu(). Fix it by checking tboot in detect_intel_iommu().

    iommufd: Avoid locking internal accesses during unmap

    In the Linux kernel, the following vulnerability has been resolved: iommufd: Avoid locking internal accesses during unmap iommufd_access_notify_unmap() skips internal accesses because they do not have an external unmap callback to invoke. However, the current test calls iommufd_lock_obj() before checking whether the access is internal. If iommufd_lock_obj() succeeds, the loop then sees the internal access and continues, bypassing the matching iommufd_put_object() used by the normal unmap path. This leaks the object reference taken by iommufd_lock_obj(). Check for internal accesses first so skipped entries are never locked.

If xa_store() fails, the current IOAS has not been inserted into ioas_list yet. iommufd_release_all_iova_rwsem() only unwinds IOAS objects already present in that xarray, so it cannot release the current IOAS. Release the current IOAS rwsem and object reference before unwinding the previously stored entries.

TRIGGER_IOPF then dereferences the freed handle, causing a UAF. Fix by adding a iopf_rwsem in mock_dev to follow the expected design of a real driver.
