| ================= |
| |
| Security Disclosures |
| -------------------- |
| |
| Trusted Firmware-M(TF-M) disclose all security vulnerabilities, or are advised |
| about, that are relevant to TF-M. TF-M encourage responsible disclosure of |
| vulnerabilities and try the best to inform users about all possible issues. |
| |
| The TF-M vulnerabilities are disclosed as Security Advisories, all of which are |
| listed at the bottom of this page. |
| |
| Found a Security Issue? |
| ----------------------- |
| |
| Although TF-M try to keep secure, it can only do so with the help of the |
| community of developers and security researchers. |
| |
| .. warning:: |
| If any security vulnerability was found, please **do not** |
| report it in the `issue tracker`_ or on the `mailing list`_. Instead, please |
| follow the `TrustedFirmware.org security incident process`_. |
| |
| One of the goals of this process is to ensure providers of products that use |
| TF-M have a chance to consider the implications of the vulnerability and its |
| remedy before it is made public. As such, please follow the disclosure plan |
| outlined in the `Security Incident Process`_. TF-M do the best to respond and |
| fix any issues quickly. |
| |
| Afterwards, write-up all the findings about the TF-M source code is highly |
| encouraged. |
| |
| Attribution |
| ----------- |
| |
| TF-M values researchers and community members who report vulnerabilities and |
| TF-M policy is to credit the contributor's name in the published security advisory. |
