If the walk\nraces with dm_table_destroy -> free_devices -> dm_put_table_device, there\nis access to invalid memory.\n\nFix this race by extending the lock over the list walk.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/00ad6f9ed27f91925d4d3fb7aab50a60d774f998","https://git.kernel.org/stable/c/0ea6e5ad4a5817e91f11b4cc1e022e575ed2e7ca","https://git.kernel.org/stable/c/5380c7f6335cc6d77eb77d065105e81155c4d9d3","https://git.kernel.org/stable/c/a1af1884c960b98c621b6fe2fea1216b78c02152","https://git.kernel.org/stable/c/af1f32ccf8051f4691ced11feb452b9d13561727"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89998","score":0.00169,"percentile":0.0619,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
