| CVE-2021-34147 | 1 Cypress | 2 Cyw20735b1, Wireless Internet Connectivity For Embedded Devices | 2021-09-14 | 6.1 MEDIUM | 6.5 MEDIUM |
| The Bluetooth Classic implementation in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 does not properly handle the reception of a malformed LMP timing accuracy response followed by multiple reconnections to the link slave, allowing attackers to exhaust device BT resources and eventually trigger a crash via multiple attempts of sending a crafted LMP timing accuracy response followed by a sudden reconnection with a random BDAddress. | |||||
| CVE-2021-34145 | 1 Cypress | 2 Cyw20735b1, Wireless Internet Connectivity For Embedded Devices | 2021-09-14 | 2.9 LOW | 5.3 MEDIUM |
| The Bluetooth Classic implementation in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 devices does not properly handle the reception of LMP_max_slot with an invalid Baseband packet type (and LT_ADDRESS and LT_ADDR) after completion of the LMP setup procedure, allowing attackers in radio range to trigger a denial of service (firmware crash) via a crafted LMP packet. | |||||
| CVE-2021-34148 | 1 Cypress | 2 Cyw20735b1, Wireless Internet Connectivity For Embedded Devices | 2021-09-14 | 6.1 MEDIUM | 6.5 MEDIUM |
| The Bluetooth Classic implementation in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 devices does not properly handle the reception of LMP_max_slot with a greater ACL Length after completion of the LMP setup procedure, allowing attackers in radio range to trigger a denial of service (firmware crash) via a crafted LMP packet. | |||||
| CVE-2021-34146 | 1 Cypress | 4 Cyw20735b1, Cyw20735b1 Firmware, Cyw920735q60evb-01 and 1 more | 2021-09-14 | 6.1 MEDIUM | 6.5 MEDIUM |
| The Bluetooth Classic implementation in the Cypress CYW920735Q60EVB does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service and restart (crash) of the device by flooding it with LMP_AU_Rand packets after the paging procedure. | |||||
