CVE-2022-49424

CVE-2022-49424 is a Linux kernel issue in the Mediatek IOMMU driver. The root cause is a NULL pointer dereference when printing dev_name due to larbdev being NULL during probe (mtk_iommu_probe_device). The crash can occur in device_link_add() and is triggered by an incorrect DTS input. The public...
