Out-of-bounds reads via unchecked HCI report lengths
Published Nov 26, 2024 · Updated Dec 6, 2024
Out-of-bounds reads in Apache NimBLE 1.7.0 and earlier allow attackers to trigger bogus GAP device-found events through malformed HCI reports. The host event parser trusts report counts and data lengths without first proving that each legacy or extended advertising record fits inside the received event buffer. Reachability requires a broken or bogus Bluetooth controller feeding malformed advertising reports to the host; the published impact is limited to out-of-bounds access and spurious discovery events.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=1.7.0
