Summary
accel/qaic: Add overflow check to remap_pfn_range during mmap
Details

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

accel/qaic: Add overflow check to remappfnrange during mmap

The call to remappfnrange in qaicgemobject_mmap is susceptible to (re)mapping beyond the VMA if the BO is too large. This can cause use after free issues when munmap() unmaps only the VMA region and not the additional mappings. To prevent this, check the remaining size of the VMA before remapping and truncate the remapped length if sg->length is too large.
