After the sync commit, re-acquire the buffers via\nmp->m_sb_bp / mp->m_rtsb_bp for the on-disk writeback.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99132","source_modified_at":"2026-10-28T10:34:45.756Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"f7664b31975bd893190708e76b2c424328f0c49b","lessThan":"e5456dec79c71c8ef8f9f9adb77d320f113b34db","status":"affected","versionType":"git"},{"version":"f7664b31975bd893190708e76b2c424328f0c49b","lessThan":"6353e5cd8c43d6e805cacbfbfecf4103571a7ff8","status":"affected","versionType":"git"},{"version":"f7664b31975bd893190708e76b2c424328f0c49b","lessThan":"41a28c865d1d5843f8cb9e0af17a8f4d9e2961ff","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99132","source_modified_at":"2026-10-28T10:34:45.756Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.18","status":"affected"},{"version":"0","lessThan":"4.18","status":"unaffected","versionType":"semver"},{"version":"6.18.59","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.13","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-2026-99132","source_modified_at":"2026-10-28T10:34:45.756Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"6353e5cd8c43d6e805cacbfbfecf4103571a7ff8","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99132","source_modified_at":"2026-10-28T10:34:45.756Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"41a28c865d1d5843f8cb9e0af17a8f4d9e2961ff","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T10:34:45.756Z","modified_at":"2026-10-28T10:34:45.756Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99132","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:34:45.756Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/e5456dec79c71c8ef8f9f9adb77d320f113b34db"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6353e5cd8c43d6e805cacbfbfecf4103571a7ff8"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/41a28c865d1d5843f8cb9e0af17a8f4d9e2961ff"}],"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":"2026-10-28T10:34:45.756Z","content_hash":"18e1ca7d42ac4afca957bce570e1296cacd66e377a06a0cd9fc4e8b7637573b6"}}
