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 on the +TF-A project's `mailing list`_. + +Found a Security Issue? +----------------------- + +Although we try to keep TF-A secure, we can only do so with the help of the +community of developers and security researchers. + +.. warning:: + If you think you have found a security vulnerability, 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-A 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 process. We do our best to respond and fix any issues quickly. + +Afterwards, we encourage you to write-up your findings about the TF-A source +code. + +Attribution +----------- + +We will name and thank you in the :ref:`Change Log & Release Notes` distributed +with the source code and in any published security advisory. + +Security Advisories +------------------- + ++-----------+------------------------------------------------------------------+ +| ID | Title | ++===========+==================================================================+ +| |TFV-1| | Malformed Firmware Update SMC can result in copy of unexpectedly | +| | large data into secure memory | ++-----------+------------------------------------------------------------------+ +| |TFV-2| | Enabled secure self-hosted invasive debug interface can allow | +| | normal world to panic secure world | ++-----------+------------------------------------------------------------------+ +| |TFV-3| | RO memory is always executable at AArch64 Secure EL1 | ++-----------+------------------------------------------------------------------+ +| |TFV-4| | Malformed Firmware Update SMC can result in copy or | +| | authentication of unexpected data in secure memory in AArch32 | +| | state | ++-----------+------------------------------------------------------------------+ +| |TFV-5| | Not initializing or saving/restoring PMCR_EL0 can leak secure | +| | world timing information | ++-----------+------------------------------------------------------------------+ +| |TFV-6| | Trusted Firmware-A exposure to speculative processor | +| | vulnerabilities using cache timing side-channels | ++-----------+------------------------------------------------------------------+ +| |TFV-7| | Trusted Firmware-A exposure to cache speculation vulnerability | +| | Variant 4 | ++-----------+------------------------------------------------------------------+ +| |TFV-8| | Not saving x0 to x3 registers can leak information from one | +| | Normal World SMC client to another | ++-----------+------------------------------------------------------------------+ +| |TFV-9| | Trusted Firmware-A exposure to speculative processor | +| | vulnerabilities with branch prediction target reuse | ++-----------+------------------------------------------------------------------+ +| |TFV-10| | Incorrect validation of X.509 certificate extensions can result | +| | in an out-of-bounds read | ++-----------+------------------------------------------------------------------+ + +.. _issue tracker: https://developer.trustedfirmware.org/project/board/1/ +.. _mailing list: https://lists.trustedfirmware.org/mailman3/lists/tf-a.lists.trustedfirmware.org/ + +.. |TFV-1| replace:: :ref:`Advisory TFV-1 (CVE-2016-10319)` +.. |TFV-2| replace:: :ref:`Advisory TFV-2 (CVE-2017-7564)` +.. |TFV-3| replace:: :ref:`Advisory TFV-3 (CVE-2017-7563)` +.. |TFV-4| replace:: :ref:`Advisory TFV-4 (CVE-2017-9607)` +.. |TFV-5| replace:: :ref:`Advisory TFV-5 (CVE-2017-15031)` +.. |TFV-6| replace:: :ref:`Advisory TFV-6 (CVE-2017-5753, CVE-2017-5715, CVE-2017-5754)` +.. |TFV-7| replace:: :ref:`Advisory TFV-7 (CVE-2018-3639)` +.. |TFV-8| replace:: :ref:`Advisory TFV-8 (CVE-2018-19440)` +.. |TFV-9| replace:: :ref:`Advisory TFV-9 (CVE-2022-23960)` +.. |TFV-10| replace:: :ref:`Advisory TFV-10 (CVE-2022-47630)` + +.. _TrustedFirmware.org security incident process: https://developer.trustedfirmware.org/w/collaboration/security_center/ + +-------------- + +*Copyright (c) 2019-2023, Arm Limited.
