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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98028","source_modified_at":"2026-10-19T09:12:33.311Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"9eb03bb1c035ff6e2c3a34046419446588253dda","lessThan":"603b70093f729f52a37544b48679903cad834856","status":"affected","versionType":"git"},{"version":"9eb03bb1c035ff6e2c3a34046419446588253dda","lessThan":"edaec279f59f801a05b751df475ed71a0a68c88a","status":"affected","versionType":"git"},{"version":"9eb03bb1c035ff6e2c3a34046419446588253dda","lessThan":"552e528a7d85cbe088b2ae4f78194713975b46cf","status":"affected","versionType":"git"},{"version":"9eb03bb1c035ff6e2c3a34046419446588253dda","lessThan":"108bb2142e3a12c9ad625ad662973127a113ddc6","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98028","source_modified_at":"2026-10-19T09:12:33.311Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.8","status":"affected"},{"version":"0","lessThan":"6.8","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98028","source_modified_at":"2026-10-19T09:12:33.311Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"603b70093f729f52a37544b48679903cad834856","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98028","source_modified_at":"2026-10-19T09:12:33.311Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"552e528a7d85cbe088b2ae4f78194713975b46cf","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98028","source_modified_at":"2026-10-19T09:12:33.311Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"108bb2142e3a12c9ad625ad662973127a113ddc6","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05734,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:23:45.737Z","modified_at":"2026-10-19T09:12:33.311Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98028","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:12:33.311Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98028","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/603b70093f729f52a37544b48679903cad834856"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/edaec279f59f801a05b751df475ed71a0a68c88a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/552e528a7d85cbe088b2ae4f78194713975b46cf"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/108bb2142e3a12c9ad625ad662973127a113ddc6"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:12:33.311Z","content_hash":"186e179d4bfbc113dbe4f69a74638f3c0ee3b44093702b4859558e7fa9bb8203"}}
