In the Linux kernel, the following vulnerability has been resolved: xfrm: xfrm_alloc_spi shouldnt use 0 as SPI x->id.spi == 0 means "no SPI assigned", but since commit 94f39804d891 ("xfrm: Duplicate SPI Handling"), we now create states and add them to the byspi list with this value. __xfrm_state_delete doesnt remove those states from the byspi list, since they shouldnt be there, and this shows up as a UAF the next time we go through the byspi list.
