Official description
In the Linux kernel, the following vulnerability has been resolved:
hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume
When the optional PRE_COPY support was added to speed up the device compatibility check, it failed to update the saving/resuming data pointers based on the fd offset. This results in migration data corruption and when the device gets started on the destination the following error is reported in some cases,
