Medium (6.5) in zh-jieli. EPSS 0.6% chance of exploitation in the next 30 days.
The Bluetooth Classic implementation on Zhuhai Jieli AC690X and AC692X devices does not properly handle the reception of a truncated LMP packet during the LMP auto rate procedure, allowing attackers in radio range to immediately crash (and restart) a device via a crafted LMP packet.
