The Bluetooth wireless technology is a worldwide specification for a small-form factor, low-cost radio solution that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. The specification is developed, published and promoted by the Bluetooth Special Interest Group (SIG).
BlueZ provides support for the core Bluetooth layers and protocols. It is flexible, efficient and uses a modular implementation. It has many interesting features:
Bluetooth kernel subsystem core (including L2CAP, SCO and RFCOMM)
HCI UART, USB, PCI-E and virtual adapter drivers
System daemon with D-Bus APIs for access and integration
Configuration and testing utilities
Protocol decoding and analysis tools
Lower level Host Stack: Core specification 4.2, Not (yet) 3.0+HS. Includes GAP, L2CAP, RFCOMM and SDP.
A security-focused week with two independent vulnerability disclosures: a use-after-free in l2cap_sock_alloc_skb_cb reported by Safa Karakuş, and an SDP OOB heap read via signed/unsigned confusion (CVSS 8.1H, no pairing required).
A landmark week marked by the BlueZ Face-to-Face Meetup announcement (Nice, France, May 30-31) and Bastien Nocera's massive meson build system v9 series (15 patches, 16 messages) proposing a complete build system migration plus HTML documentation generation.
A week dominated by Naga Bhavani Akella's extraordinary Channel Sounding iteration — posting v3 through v10 (8 revisions, 32 messages) of the BlueZ Channel Sounding implementation, making her the most prolific contributor by a wide margin.
