2021-09-07	CVE-2021-31611	Improper Locking vulnerability in Zh-Jieli products 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. low complexity zh-jieli CWE-667	5.7
2021-09-07	CVE-2021-31612	Unspecified vulnerability in Zh-Jieli products The Bluetooth Classic implementation on Zhuhai Jieli AC690X devices does not properly handle the reception of an oversized LMP packet greater than 17 bytes during the LMP auto rate procedure, allowing attackers in radio range to trigger a deadlock via a crafted LMP packet. low complexity zh-jieli	6.5
2021-09-07	CVE-2021-31613	Unspecified vulnerability in Zh-Jieli products 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. low complexity zh-jieli	6.5
