A user\nmapped buffer has resizing disabled, and __rb_map_vma() reads\nbuffer->subbuf_order without buffer->mutex, so an mmap of an already\nmapped CPU racing the failing order change sizes the mapping with the\nnew order and inserts pages past the sub-buffer into the VMA.\n\nCheck the CPUs before storing the new order.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97617","source_modified_at":"2026-10-19T09:10:20.808Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"117c39200d9d760cbd5944bb89efb7b9c51965aa","lessThan":"f2099644e1b2a2c0805c5240d63ab0522d9d0174","status":"affected","versionType":"git"},{"version":"117c39200d9d760cbd5944bb89efb7b9c51965aa","lessThan":"9fd4ea952e6ac12a63c3fe89f08ad02771aa2c06","status":"affected","versionType":"git"},{"version":"117c39200d9d760cbd5944bb89efb7b9c51965aa","lessThan":"32bf47db9237c5b8b6f6aaa5356bb4c79d241f76","status":"affected","versionType":"git"},{"version":"117c39200d9d760cbd5944bb89efb7b9c51965aa","lessThan":"d860c67c051685abb0460b593b193f0f45f4fa92","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97617","source_modified_at":"2026-10-19T09:10:20.808Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.10","status":"affected"},{"version":"0","lessThan":"6.10","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-2026-97617","source_modified_at":"2026-10-19T09:10:20.808Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"9fd4ea952e6ac12a63c3fe89f08ad02771aa2c06","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97617","source_modified_at":"2026-10-19T09:10:20.808Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"32bf47db9237c5b8b6f6aaa5356bb4c79d241f76","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09309,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:22:24.436Z","modified_at":"2026-10-19T09:10:20.808Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97617","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:10:20.808Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97617","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/f2099644e1b2a2c0805c5240d63ab0522d9d0174"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/9fd4ea952e6ac12a63c3fe89f08ad02771aa2c06"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/32bf47db9237c5b8b6f6aaa5356bb4c79d241f76"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d860c67c051685abb0460b593b193f0f45f4fa92"}],"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":"2026-10-19T09:10:20.808Z","content_hash":"39e65a761d2aa30375907b9f782dc60fe2feaf0039081cb20d1563bcd0158a2e"}}
