We disclose all security vulnerabilities we find, or are advised about, that are relevant to Trusted Firmware-A. We encourage responsible disclosure of vulnerabilities and inform users as best we can about all possible issues.
We disclose TF-A vulnerabilities as Security Advisories, all of which are listed at the bottom of this page. Any new ones will, additionally, be announced as issues in the project's issue tracker with the security-advisory tag. You can receive notification emails for these by watching the "Trusted Firmware-A" project at https://developer.trustedfirmware.org/.

If you would like replies to be encrypted, please provide your public key.
Please give us the time to respond to you and fix the vulnerability before going public. We do our best to respond and fix any issues quickly. We also need to ensure providers of products that use TF-A have a chance to consider the implications of the vulnerability and its remedy.
Afterwards, we encourage you to write-up your findings about the TF-A source code.
We will name and thank you in the change-log.rst distributed with the source code and in any published security advisory.
