5.7 mediumCVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:HCVE-2021-31611
Medium (5.7) in zh-jieli. EPSS 0.4% chance of exploitation in the next 30 days.
The Bluetooth Classic implementation on Zhuhai Jieli AC690X and AC692X devices does not properly handle an out-of-order LMP Setup procedure that is followed by a malformed LMP packet, allowing attackers in radio range to deadlock a device via a crafted LMP packet. The user needs to manually reboot the device to restore communication.
