If\nnfp_net_fs_add_hw() fails the old entry stays on nn->fs.list - only the\nsuccess path reaches list_replace() - so the list is one longer than\nnn->fs.count, and it advertises a rule whose hardware entry has already\nbeen torn down.\n\nnn->fs.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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/108bb2142e3a12c9ad625ad662973127a113ddc6","tags":[]},{"url":"https://git.kernel.org/stable/c/552e528a7d85cbe088b2ae4f78194713975b46cf","tags":[]},{"url":"https://git.kernel.org/stable/c/603b70093f729f52a37544b48679903cad834856","tags":[]},{"url":"https://git.kernel.org/stable/c/edaec279f59f801a05b751df475ed71a0a68c88a","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
