  "description": "In the Linux kernel, the following vulnerability has been resolved:  iommu/omap: Fix regression in probe for NULL pointer dereference  Commit 3f6634d997db (\u0022iommu: Use right way to retrieve iommu_ops\u0022) started triggering a NULL pointer dereference for some omap variants:  __iommu_probe_device from probe_iommu_group\u002B0x2c/0x38 probe_iommu_group from bus_for_each_dev\u002B0x74/0xbc bus_for_each_dev from bus_iommu_probe\u002B0x34/0x2e8 bus_iommu_probe from bus_set_iommu\u002B0x80/0xc8 bus_set_iommu from omap_iommu_init\u002B0x88/0xcc omap_iommu_init from do_one_initcall\u002B0x44/0x24  This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV) as noted by Jason Gunthorpe \u003Cjgg@ziepe.ca\u003E.  Looks like the regression already happened with an earlier commit 6785eb9105e3 (\u0022iommu/omap: Convert to probe/release_device() call-backs\u0022) that changed the function return type and missed converting one place.",
