PatchTheCVECVE-2022-23822: In this physical attack, an attacker may potentially exploit the Zynq-7000 SoC First Stage Boot Loader (FSBL)
CVE-2022-23822 is a medium-severity flaw (CVSS 6.8) affecting zynq-7000s firmware, zynq-7000 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In this physical attack, an attacker may potentially exploit the Zynq-7000 SoC First Stage Boot Loader (FSBL) by bypassing authentication and loading a malicious image onto the device. This in turn may further allow the attacker to perform additional attacks such as such as using the device as a decryption oracle. An anticipated mitigation via a 2022.1 patch will resolve the issue.
