CVE-2026-44634
Stack buffer overflows in SimpleBLE
Description

SimpleBLE is a cross-platform library and bindings for Bluetooth Low Energy (BLE). Prior to version 0.14.0, there are multiple stack-based buffer overflow vulnerabilities in SimpleBLE. There is a stack overflow vulnerability in the dongl backend’s Protocol::simpleble_write function (local, caller-controlled input). A stack overflow vulnerability when processing manufacturer-specific data in BLE advertisements (remote, no pairing or connection required). Lastly, a stack overflow vulnerability when processing service data in BLE advertisements (remote, no pairing or connection required). This issue has been patched in version 0.14.0.
