Hi,
As it was mentioned in this discussion:
https://community.cypress.com/t5/ModusToolbox-Bluetooth-SDK/CYW20819-Braktooth/m-p/288395#M2065
There is an issue from Braktooth for CYW20735 which affects CYW20819 as well (https://community.cypress.com/t5/Security-Bulletin/Bluetooth-Denial-of-Service-Vulnerabilities-Brakt...).
The said patch "will be available in BTSDK 3.2 (available in late Q4 2021)".
My questions are:
1) Will this vulnerability affects devices CYW43353 and CYW4343W?
2) When will a patch be available for devices CYW43353 and CYW4343W, and what form will it take?
Thank you.
Solved! Go to Solution.

Hi,
This vulnerability affects only the Bluetooth Classic. Are you using these chips for any Bluetooth Classic applications?

Hi @DheerajPK_41,
In case we are using Bluetooth Classic with CYW43xxx, will a patch be available for those devices (CYW43353 and CYW4343W) and what form will it take?
Thank you.

Hi,
You can get the patched HCD files from us or module vendor. The fixes are currently under validation. Please create a salesforce case or contact our sales team to get the patched firmware.
