Running\nthe list_empty() test and the list_del_init() outside of the lock may\ntherefore corrupt either list.\n\nPerform both under bridge_lock.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98973","source_modified_at":"2026-10-23T12:19:46.458Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"17805a15d1751f5d6bb06f924f9bed216feb8db7","lessThan":"f469d850854101eae60dd4080244f114a9bcf2b5","status":"affected","versionType":"git"},{"version":"17805a15d1751f5d6bb06f924f9bed216feb8db7","lessThan":"b62e3db8cdc1680e1c3390591e872f485148541a","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98973","source_modified_at":"2026-10-23T12:19:46.458Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.19","status":"affected"},{"version":"0","lessThan":"6.19","status":"unaffected","versionType":"semver"},{"version":"7.2.11","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T12:19:46.458Z","modified_at":"2026-10-23T12:19:46.458Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98973","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:19:46.458Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/f469d850854101eae60dd4080244f114a9bcf2b5"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b62e3db8cdc1680e1c3390591e872f485148541a"}],"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":"2026-10-23T12:19:46.458Z","content_hash":"2133f845f10e3cddc43caa2c05f3c3c615fcc313a15295209137d515def788a7"}}
