| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 3.3 |
| 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 | 6.1 |
| 2021-09-07 | CVE-2021-34143 | Unspecified vulnerability in Zh-Jieli Fw-Ac63 BT SDK 1.0.0 The Bluetooth Classic implementation in the Zhuhai Jieli AC6366C_DEMO_V1.0 does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service (deadlock) of the device by flooding it with LMP_AU_Rand packets after paging procedure. low complexity zh-jieli | 6.1 |
| 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 | 3.3 |
| 2021-09-07 | CVE-2021-34144 | Unspecified vulnerability in Zh-Jieli Fw-Ac63 BT SDK The Bluetooth Classic implementation in the Zhuhai Jieli AC6366C BT SDK through 0.9.1 does not properly handle the reception of truncated LMP_SCO_Link_Request packets while no other BT connections are active, allowing attackers in radio range to prevent new BT connections (disabling the AB5301A inquiry and page scan procedures) via a crafted LMP packet. low complexity zh-jieli | 3.3 |
