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.
AnalysisAI
Buffer overflow in Apache NimBLE's HCI socket transport (through version 1.9.0) allows an adjacent attacker with a malicious or compromised Bluetooth controller to execute arbitrary code on the host by sending an oversized HCI event. Exploitation requires either a misconfigured event pool size or control of the controller on the HCI link, not over-the-air Bluetooth access. No active exploitation or public exploit code is known, and the real-world risk is low despite a CVSS 7.5 rating.
