🛡️ AZL-64613 — kernel (CVE-2025-38158)

CVE-2025-38158 affecting package kernel for versions less than 6.6.96.1-1

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.
