CVE-2026-89452

CVE-2026-89452 affects the iommu/msm driver in the Linux kernel. The root cause is an improper error-handling path in msm_iommu_probe(): when iommu_device_sysfs_add() or iommu_device_register() fails, the IOMMU object is left in the global qcom_iommu_devices list after its devm-managed memory has...

CVE-2026-89452 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 msmiommuprobe adds its devm-managed IOMMU object to qcomiommudevices before adding the IOMMU sysfs device and registering it with the IOMMU core. If iommudevicesysfsadd fails,...

CVE-2026-89451

CVE-2026-89451 is a race condition in the Linux kernel 's iommu/sva subsystem. iommu_attach_device_pasid() installs the SVA attach handle into the group PASID lookup before iommu_sva_bind_device() returns, allowing a concurrent bind to find and reuse the handle after iommu_sva_lock is dropped. Ho...
