CVE-2021-47325

CVE-2021-47325 concerns the Linux kernel’s iommu/arm-smmu subsystem. The issue is a refcount leak in arm_smmu_iova_to_phys_hard() where, on several error paths, the refcount of the underlying smmu object, increased by arm_smmu_rpm_get(), is not decremented. The fixed workaround described in the p...
