[dpdk-dev] [PATCH] mem: fix use after free in legacy mem init

> Adding an additional failure path in DMA mask check has exposed an
> issue where `hugepage` pointer may point to memory that has already
> been unmapped, but pointer value is still not NULL, so failure
> handler will attempt to unmap it second time if DMA mask check
> fails. Fix it by setting `hugepage` pointer to NULL once it is no
> longer needed.
