      "title": "xfrm: fix compat ALLOCSPI request use-after-free",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfrm: fix compat ALLOCSPI request use-after-free\n\nxfrm_state_netlink() builds the ALLOCSPI response with\ndump_one_state(), which already calls alloc_compat() with the response\nskb and header.\n\nxfrm_alloc_userspi() then calls alloc_compat() again, but passes the\noriginal request skb and its header. For a compat request, the\ntranslator therefore interprets the 228-byte compat xfrm_userspi_info\nas the 232-byte native layout and reads four bytes past the declared\npayload. It also publishes the translated child through the request's\nfrag_list.\n\nA multicast clone of the request shares skb_shared_info and can observe\nthat child. xfrm_user_rcv_msg() frees it after the request handler\nreturns, racing a compat receiver which may still be copying from it and\nresulting in a use-after-free.\n\nRemove the redundant conversion. The response keeps its correct compat\ntranslation from dump_one_state(), and no child is attached to the\ninbound request.",
