CVE-2026-90243

CVE-2026-90243 is a race condition in the Linux kernel's VT-d IOMMU driver. The function copied_context_tear_down() zeroes a 128-bit context entry while the Present bit is still set , creating a window where the IOMMU hardware can fetch a torn entry —some fields zeroed while Present remains set. ...

CVE-2026-90242

CVE-2026-90242 affects the Linux kernel iommu/vt-d subsystem. When an IOMMU domain is replaced at RID level , the iopf_refcount for the old domain is never decremented. Both intel_iommu_attach_device() and identity_domain_attach_dev() enable IOPF for the new domain but fail to disable it for the ...

CVE-2026-90241

CVE-2026-90241 is a use-after-free vulnerability in the Linux kernel 's Intel VT-d IOMMU driver (iommu/vt-d). When intel_pasid_setup_sm_context() fails partway through programming scalable-mode context entries for a PCI device's DMA aliases, the probe failure path in intel_iommu_probe_device() fr...

CVE-2026-90240

CVE-2026-90240 is a Linux kernel vulnerability in the Intel VT-d IOMMU driver. When tearing down DMA aliases, the functions domain_context_clear_one() and device_pasid_table_teardown() issued a context-cache invalidation using the device's own requester ID rather than the alias's bus/devfn . This...
