In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr()
If the number of pages from the userptr BO differs from the SG BO then the
allocated memory for the SG table doesn't get freed before returning
-EINVAL, which may lead to a memory leak in some error paths. Fix this by
checking the number of pages before allocating memory for the SG table.
