{"schema_version": "1.6.1", "id": "CVE-2026-45811", "summary": "Buffer overflow in socket HCI transport", "details": "Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Apache NimBLE.\nThe HCI socket transport did not check whether a received HCI event would fit the configured event pool before copying it, allowing a buffer overflow. Severity is low: exploitation requires either a misconfigured pool size or a malicious/compromised controller on the other end of the HCI socket link, not over-the-air Bluetooth access.\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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0"}, {"last_affected": "0"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/mynewt-nimble/commit/dcc4e4f026109eecd507de9479bb5019306a4a41"}, {"type": "WEB", "url": "https://lists.apache.org/thread/5mkz68y1py0o6zmxtc3l1o8grtrb78m0"}]}
