CVE-2025-38158
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
hisi_acc_vfio_pci: fix XQE dma address error
The dma addresses of EQE and AEQE are wrong after migration and results in guest kernel-mode encryption services failure. Comparing the definition of hardware registers, we found that there was an error when the data read from the register was combined into an address. Therefore, the address combination sequence needs to be corrected.
Even after fixing the above problem, we still have an issue where the Guest from an old kernel can get migrated to new kernel and may result in wrong data.

In order to ensure that the address is correct after migration, if an old magic number is detected, the dma address needs to be updated.

Al comparar la definición de los registros de hardware, descubrimos que se producía un error al combinar los datos leídos del registro en una dirección. Por lo tanto, es necesario corregir la secuencia de combinación de direcciones. Incluso tras corregir el problema anterior, sigue existiendo un problema en el que el invitado de un kernel antiguo puede migrarse al nuevo, lo que puede generar datos erróneos. Para garantizar que la dirección sea correcta después de la migración, si se detecta un número mágico antiguo, es necesario actualizar la dirección dma."
