About this tag
The bluetooth sco tag on WindowsForum.com covers discussions about the Bluetooth SCO (Synchronous Connection-Oriented) protocol, which is used for audio streaming in Bluetooth headsets and hands-free devices. Content includes technical analysis of a Linux kernel use-after-free vulnerability (CVE-2026-31408) in the SCO path, specifically in the sco_recv_frame() function, where a race condition can lead to memory safety issues. The fix involves using sco_sock_hold() to properly manage socket references. While the tag is Linux-focused, it is relevant to Windows users interested in Bluetooth audio reliability and kernel-level security issues that may affect cross-platform Bluetooth implementations.
