{"schema":"threatline.record/2","record":{"id":"CVE-2026-97552","aliases":[],"summary":"xfs: initialise error in xfs_defer_finish_one()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: initialise error in xfs_defer_finish_one()\n\nxfs_defer_finish_one() declares error without an initialiser and only\nassigns it inside the loop over dfp->dfp_work.  When that list is empty\nthe loop body never runs, control falls through to the \"Done with the\ndfp, free it\" path, and the function returns an indeterminate value.\n\nAn item-less pending item reaches this through xfs_defer_add_barrier(),\nwhich xfs_reap_ag_blocks() uses on any CONFIG_XFS_ONLINE_REPAIR kernel.\nxfs_defer_finish_noroll() treats any non-EAGAIN return as fatal, so a\nnon-zero stack value turns a successful barrier into a\nSHUTDOWN_CORRUPT_INCORE in the middle of a repair.  Zero is the correct\nresult: reaching the free path means the item loop drained without a\nnon-zero error.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97552","source_modified_at":"2026-10-19T09:09:15.341Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"3f3cec031099c37513727efc978a12b6346e326d","lessThan":"30748a24b9f04f9a83599ba907cc8fbff0729f3c","status":"affected","versionType":"git"},{"version":"3f3cec031099c37513727efc978a12b6346e326d","lessThan":"ba949a14446b7346e92e676ee3fe2bb79d9ce450","status":"affected","versionType":"git"},{"version":"3f3cec031099c37513727efc978a12b6346e326d","lessThan":"6b507c239884f7d4bf8339f6e9eb8bfcb540afde","status":"affected","versionType":"git"},{"version":"3f3cec031099c37513727efc978a12b6346e326d","lessThan":"6176d21d7bd609632c5b7e87a3adb9be29ec1e72","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97552","source_modified_at":"2026-10-19T09:09:15.341Z","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-2026-97552","source_modified_at":"2026-10-19T09:09:15.341Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"30748a24b9f04f9a83599ba907cc8fbff0729f3c","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97552","source_modified_at":"2026-10-19T09:09:15.341Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6b507c239884f7d4bf8339f6e9eb8bfcb540afde","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97552","source_modified_at":"2026-10-19T09:09:15.341Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6176d21d7bd609632c5b7e87a3adb9be29ec1e72","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.0934,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:21:44.651Z","modified_at":"2026-10-19T09:09:15.341Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97552","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:09:15.341Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97552","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/30748a24b9f04f9a83599ba907cc8fbff0729f3c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ba949a14446b7346e92e676ee3fe2bb79d9ce450"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6b507c239884f7d4bf8339f6e9eb8bfcb540afde"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6176d21d7bd609632c5b7e87a3adb9be29ec1e72"}],"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":"2026-10-19T09:09:15.341Z","content_hash":"21a6dab0f9aada423f3d2f1e55591850b56d6c8f4a2252661886338a424becc0"}}
