CVE-2023-53789

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

iommu/amd: Improve page fault error reporting

If IOMMU domain for device group is not setup properly then we may hit IOMMU page fault. Current page fault handler assumes that domain is always setup and it will hit NULL pointer derefence (see below sample log).

Lets check whether domain is setup or not and log appropriate message.
