  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\neth: nfp: drop the replaced rule from the list when reprogramming fails\n\nnfp_net_fs_add() replaces an existing rule by deleting it from the\nhardware, decrementing nn-\u003efs.count and programming the new one.  If\nnfp_net_fs_add_hw() fails the old entry stays on nn-\u003efs.list - only the\nsuccess path reaches list_replace() - so the list is one longer than\nnn-\u003efs.count, and it advertises a rule whose hardware entry has already\nbeen torn down.\n\nnn-\u003efs.count is what ETHTOOL_GRXCLSRLCNT reports, so userspace then sizes\nits buffer one entry short of what the GRXCLSRLALL walk wants to write.\nThat used to overwrite one u32 past the allocation; since the walk is\nbounded it is a permanent -EMSGSIZE instead, as nothing ever resyncs the\ncounter.",
