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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/108bb2142e3a12c9ad625ad662973127a113ddc6","https://git.kernel.org/stable/c/552e528a7d85cbe088b2ae4f78194713975b46cf","https://git.kernel.org/stable/c/603b70093f729f52a37544b48679903cad834856","https://git.kernel.org/stable/c/edaec279f59f801a05b751df475ed71a0a68c88a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-98028","score":0.00168,"percentile":0.06023,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
