This can cause the host to read past the end of the buffer and deliver a GAP event with bogus data to the application.\n\nSeverity is low: NimBLE's own controller never batches multiple reports into one event, so this only matters when NimBLE's host is paired with a third-party controller that does.\n\nThis issue affects Apache NimBLE: through 1.9.0.\n\nUsers are recommended to upgrade to version 1.10.0, which fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-131"],"references":["https://github.com/apache/mynewt-nimble/commit/605c7585408bc3674818eeb7b6f478a8aefe9746","https://lists.apache.org/thread/rll5m1ly2vg8jr76lp5ohrtspr5vlofy","http://www.openwall.com/lists/oss-security/2026/07/24/12"],"products":["apache:nimble"],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-45812","score":0.00694,"percentile":0.52653,"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).
