      "title": "ila: reload IPv6 header after pskb_may_pull in checksum adjust",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nila: reload IPv6 header after pskb_may_pull in checksum adjust\n\nila_csum_adjust_transport() caches ip6h = ipv6_hdr(skb) before calling\npskb_may_pull(). On a non-linear skb whose transport header sits in a page\nfragment, pskb_may_pull() can call __pskb_pull_tail() / pskb_expand_head()\nand free the old skb head, leaving ip6h dangling; the following\nget_csum_diff(ip6h, p) then reads freed memory. ila_update_ipv6_locator()\nuses ip6h (and the iaddr derived from it) again after the csum-adjust\ncall and additionally writes the new locator through that pointer.\n\nImpact: a remote IPv6 packet routed through a configured ILA\ncsum-adjust-transport route or receive-side mapping triggers a\nslab-use-after-free in ila_update_ipv6_locator() (KASAN). The route or\nmapping requires CAP_NET_ADMIN to configure, but trigger packets are\nunauthenticated once it exists.\n\nReload ip6h after each pskb_may_pull() in ila_csum_adjust_transport()\nbefore the csum-diff read. In ila_update_ipv6_locator() only the\nILA_CSUM_ADJUST_TRANSPORT case pulls the skb, so reload ip6h and iaddr in\nthat case alone before the destination-address write; the neutral-map\nmodes never pull and keep their cached pointers.",
