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

ice: fix use-after-free in dynamic port cleanup

icedeallocdynamicport() uses dynport->vsi->idx to erase the dynamic port from pf->dynports. However, it frees the VSI before reading the index for the erase, resulting in a use-after-free.

Follow the reverse of the allocation order in iceallocdynamicport() by erasing the xarray entry before freeing the VSI.
