CVE-2025-38158

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> hisi_acc_vfio_pci: fix XQE dma address error<br /> <br /> The dma addresses of EQE and AEQE are wrong after migration and<br /> results in guest kernel-mode encryption services failure.<br /> Comparing the definition of hardware registers, we found that<br /> there was an error when the data read from the register was<br /> combined into an address. Therefore, the address combination<br /> sequence needs to be corrected.<br /> <br /> Even after fixing the above problem, we still have an issue<br /> where the Guest from an old kernel can get migrated to<br /> new kernel and may result in wrong data.<br /> <br /> In order to ensure that the address is correct after migration,<br /> if an old magic number is detected, the dma address needs to be<br /> updated.
