Description
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu: Fix arm_smmu_device refcount leak in address translation
The reference counting issue happens in several exception handling paths
of arm_smmu_iova_to_phys_hard(). When those error scenarios occur, the
function forgets to decrease the refcount of "smmu" increased by
arm_smmu_rpm_get(), causing a refcount leak.
Fix this issue by jumping to "out" label when those error scenarios
occur.
