A buffer overflow vulnerability exists in Apache NimBLE through version 1.9.0 due to improper size checking when copying received HCI events into the event pool. Exploitation requires a misconfigured event pool size or a malicious/compromised controller on the HCI socket link, and cannot be triggered via over-the-air Bluetooth access. The vulnerability is fixed in version 1.10.0.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Apache NimBLE. The 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. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.
