CVE-2022-23822

6.8 mediumEPSS 0.3%

Medium (6.8) in xilinx. EPSS 0.3% chance of exploitation in the next 30 days.

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.
