CVE-2022-23822 (GCVE-0-2022-23822)

Vulnerability from cvelistv5 – Published: 2022-04-27 16:06 – Updated: 2024-09-16 22:25
VLAI?
Summary
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.
Severity ?
