CyberRota Analysis

AI-Generated

Apache NimBLE versions up to 1.9.0 are vulnerable due to an incorrect calculation of buffer size when processing bundled HCI advertising report events, potentially leading to the delivery of erroneous data to applications. This vulnerability primarily impacts users who pair NimBLE's host with third-party controllers that may batch multiple reports, making it essential for those environments to prioritize upgrading to version 1.10.0 to mitigate the risk.

Original NVD Description

Incorrect Calculation of Buffer Size vulnerability in Apache NimBLE when processing Legacy Advertising Report HCI event. When a single HCI advertising report event bundles multiple reports, NimBLE miscalculated the offset to the next report. This can cause the host to read past the end of the buffer and deliver a GAP event with bogus data to the application. Severity 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. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.
