  "message": "ipv4: fix null-deref in ipv4_link_failure\n\n[ Upstream commit 0113d9c9d1ccc07f5a3710dac4aa24b6d711278c ]\n\nCurrently, we assume the skb is associated with a device before calling\n__ip_options_compile, which is not always the case if it is re-routed by\nipvs.\nWhen skb-\u003edev is NULL, dev_net(skb-\u003edev) will become null-dereference.\nThis patch adds a check for the edge case and switch to use the net_device\nfrom the rtable when skb-\u003edev is NULL.\n\nBUG\u003db/304963328\nTEST\u003dpresubmit\nRELEASE_NOTE\u003dFixes CVE-2023-42754 in the Linux kernel.\n\nFixes: ed0de45a1008 (\"ipv4: recompile ip options in ipv4_link_failure\")\nSuggested-by: David Ahern \u003cdsahern@kernel.org\u003e\nSigned-off-by: Kyle Zeng \u003czengyhkyle@gmail.com\u003e\nCc: Stephen Suryaputra \u003cssuryaextr@gmail.com\u003e\nCc: Vadim Fedorenko \u003cvfedorenko@novek.ru\u003e\nReviewed-by: David Ahern \u003cdsahern@kernel.org\u003e\nSigned-off-by: David S.
