If the\ndevice is reset and reinitialized with a smaller disksize before lock\nacquisition, nr_pages still describes the old table.  The subsequent loop\ncan then call slot_lock() past the end of the newly allocated table.\n\nRead disksize after acquiring dev_lock and checking that the device is\ninitialized.  The read lock then keeps the table and its bound stable for\nthe duration of the scan.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/391f057f44a51cc9418da5cba78b014324174264","https://git.kernel.org/stable/c/5e458fa714a55b6b64a9fe0c6d4fa609609f9ec3","https://git.kernel.org/stable/c/6d52c1f43ff39ea1ebf8f016e847677f0b60cf2b","https://git.kernel.org/stable/c/e7dbcb7a561a21e9a8f5b5fa90bb95aefbd0739d","https://git.kernel.org/stable/c/f5e9f3a75efc774f17ab3f33826630d7fe30c7ea"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-89719","score":0.00168,"percentile":0.0615,"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).
