CVE-2026-79379

Service interruption via crafted SBC audio frame

Published Sep 8, 2026 · Updated Sep 8, 2026

Buffer overflow in Bestechnic BES2300 firmware 3.x and earlier allows attackers to interrupt Bluetooth audio processing via a crafted frame. The SBC_DecodeFrames() function overflows a buffer while decoding the attacker-supplied frame; the specific missing bounds check is undisclosed. Reachability requires delivery of a crafted SBC audio frame, and the published record does not identify the interruption as a hang, crash, or reboot.
